Perl::Critic::Policy::RegularExpressions::ProhibitCaptureWithoutTest
If a regexp match fails, then any capture variables ($1
, $2
,
...) will be undefined. Therefore it's important to check the return
value of a match before using those variables.
This policy checks that capture variables are inside a conditional and do not follow an regexps.
This policy does not check whether that conditional is actually testing a regexp result, nor does it check whether a regexp actually has a capture in it. Those checks are too hard.
