I'm in the process of porting to VAXLISP and I've come across one
thing that I think should be changed. In PCL, #+3600 is used for
3600 specific code. VAXLISP dies on this since 3600 is not a symbol.
The commonlisp book (Steele) also says that #+ items must be symbols.
It's not so gross to force the #+/#- reader to intern all tokens;
|3600| is a perfectly good symbol. Besides, if we were to allow
numbers in #+/#- expressions, we'd be back to the problem found
soon after the first existence of the 3600, in which a change of
the read base caused #+/#- conditionals to fail . . .
I think it's too restrictive to not allow "fixnum symbols" in #
