RE: scanner bug (was: cons 2.1.2 issues)

[Peter Vogel]

Yes, do {} while (<cond>); is
really just a variation of all the postfix
conditional operators.  do {}; is a statement,
just like "print;" is a statement, so

do {} while (<cond>); is no different than, for
example:

print if (/pattern/);

Been around for a long long time.
