Why would you *not* want to? You've just made "#" asymmetric in its
behaviour; in the meantime the parser just sees an unescaped "#" and
ignores everything after that, without regard to context.
You might also be using "script" e.g.
script
blah blah
# Now here I do something funky
*really* funky stuff

Funny; I recall ALGOL using "comment ... ;" or was that ALGOLW (which I
loved using; I wish I still had my ALGOLW book)?
