If so, the quality of Lisp advocacy has suffered a precipitous decline since
my day <wink>. I spend less time puzzling over syntax errors in Python than
I spent tracking down stuttered or missing parens in Lisp code, and in the
presence of read macros errors in Lisp input can be arbitirarily difficult
to spot. I routinely spend gobs of time trying to figure out what's wrong
in C source, though -- e.g., forget a semicolon after a struct declaration
and it's likely to take the next identifier as declaring a variable of the
struct type, and the subsequent cascade of nonsensical error msgs is truly
amazing. Lisp is mounds better than C in that respect -- but so is Python.
