Negating a symbol such as -x seems "un-Scheme" like.
You can't negate a symbol with -x in Scheme. Try it. You'll find that "-x" is an unbound variable. However -5 is valid notation for a negative integer. It's part of the number itself, not parsed as a negation.
I would think that proper prefix notation would demand (- x).
Isn't that right?
That is the correct notation. Dave -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-lpsg
