Subject: Generate binop comparators on the fly
X-Git-Tag: v0.01~23
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FTest-Leaner.git;a=commitdiff_plain;h=95d98c140e711be6185a7ff61ac78668ebc91155

Generate binop comparators on the fly

Except for is_like() and is_unlike() which are needed for like() and
unlike().

This should also make cmp_ok() a little faster since we don't have to
resolve the symbolic reference at each run.
