It turns out that when you read a source code file that the
inner loop of the parser does a lot of superfluous checking
of PORT? Although PORT? is an inexpensive operation,
it still involves an out-of-line call, and it gets called eleven times
for each character of input.

Just pushed a few more changes. I wrote a simple benchmark which just
involved reading 97800 symbols from a file. (The symbols were already
interned). Before these latest changes, the median speed was 13872
symbols per second. These last changes put us at 14662 symbols per
second. (For compari
Might be nice to have the benchmark in the tests directory.
