NAME

Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit

DESCRIPTION

The split function always interprets the PATTERN argument as a regular expression, even if you specify it as a string. This causes much confusion if the string contains regex metacharacters. So for clarity, always express the PATTERN argument as a regex.

  $string = 'Fred|Barney';
  @names = split '|', $string; #not ok, is ('F', 'r', 'e', 'd', '|', 'B', 'a' ...)
  @names = split m/[|]/, $string; #ok, is ('Fred', Barney')

When the PATTERN is a single space the split function has special behavior, so Perl::Critic forgives that usage. See "perldoc -f split" for more information.
