all look-ups into the vocabulary failed on wide unicode builds, which
further meant that the part-of-speech tagger and parser features were not
computed correctly.
The fix is simple: we already have to read in a list of all the strings, so
just store an index into that list, instead of a hash.
* Parse tree navigation API was rough, and buggy.

The parse-tree navigation API was the last thing I added before v0.3. I've
now replaced it with something better. The previous API design was flawed,
and the implementation was buggy --- Token.child() and Token.head were
sometimes inconsistent.
I've addressed the most immediate problems, but this part of the design is
still a work in progress. It's a difficult problem. The parse is a tree,
still a work in progress. It's a difficult problem. The parse is a tree,
and we want to freely navigate up and down it without creating reference
cycles that inhibit garbage collection, and without doing a lot of copying,
creating and deleting.
I think I've got a promising solution to this, but I suspect there's
currently a memory leak. Please get in touch no the tracker if you want to
know more, especially if you think you can help.

Most English parsing research is performed on text with perfect pre-processing:
one newline between every sentence, one space between every token.
It's always been done this way, and it's good. It's a useful idealisation,
because the pre-processing has few algorithmic implications.
But, for practical performance, this stuff can matter a lot.

The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields.

[ 14 ] Chemically , about three quarters of the Sun 's mass consists of hydrogen , while the rest is mostly helium. The remaining 1.69 % ( equal to 5 , 600 times the mass of Earth ) consists of heavier elements , including oxygen , carbon , neon and iron , among others. [ 15 ]
The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. [ 12 ] [ 13 ] It has a diameter of about 1 , 392 , 684 km ( 865 , 374 mi ) , [ 5 ] around 109 times that of Earth , and its mass ( 1.989×1030 kilograms , approximately 330 , 000 times the mass of Earth ) accounts for about 99.86 % of the total mass of the Solar System.

The remaining 1.69 % ( equal to 5 , 600 times the mass of Earth ) consists of heavier elements , including oxygen , carbon , neon and iron , among others. [ 15 ]
The Sun formed about 4.567 billion [ a ] [ 16 ] years ago from the gravitational collapse of a region within a large molecular cloud. Most of the matter gathered in the center , while the rest flattened into an orbiting disk that would become the Solar System. The central mass became increasingly hot and dense , eventually initiating thermonuclear fusion in its core. It is thought that almost all stars form by this process. The Sun is a G-type main-sequence star ( G2V ) based on spectral class and it is informally designated as a yellow dwarf because its visible radiation is most intense in the yellow-green portion of the spectrum , and although it is actually white in color , from the surface of the Earth it may appear yellow because of atmospheric scattering of blue light. [ 17 ] In the spectral class label , G2 indicates its surface temperature , of approximately 5778 K ( 5505 °C ) , and V indicates that the Sun , like most stars , is a main-sequence star , and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core , the Sun fuses about 620 million metric tons of hydrogen each second. [ 18 ] [ 19 ]
Once regarded by astronomers as a small and relatively insignificant star , the Sun is now thought to be brighter than about 85 % of the stars in the Milky Way , most of which are red dwarfs. [ 20 ] [ 21 ] The absolute magnitude of the Sun is +4.83 ; however , as the star closest to Earth , the Sun is by far the brightest object in the sky with an apparent magnitude of −26.74. [ 22 ] [ 23 ] This is about 13 billion times brighter than the next brightest star , Sirius , with an apparent magnitude of −1.46. The Sun 's hot corona continuously expands in space creating the solar wind , a stream of charged particles that extends to the heliopause at roughly 100 astronomical units. The bubble in the interstellar medium formed by the solar wind , the heliosphere , is the largest continuous structure in the Solar System. [ 24 ] [ 25 ]
