I've noticed that the number of characters in the set 'A' through 'Z',
'a' through 'z', '0' through '9', and '_' total 63.  These are the
characters used to specify variables in C.  Interesting--when you include
'\0' you get 64, a nice power of 2.  Could this tidbit be of any use to
the C compiler builders?
