Perl::Critic::Policy::Lax::ProhibitEmptyQuotes::ExceptAsFallback - empty quotes are okay as the fallback on the rhs of ||
version 0.009
Sure, "" can be confusing when crammed into the middle of a big list of values, and a bunch of spaces is even worse. It's really common, though, to write this code to get a default, false, defined string:
""
my $value = $got || '';
It's got a certain charm about it that just isn't manifested by these:
my $value = $got || $EMPTY; my $value = $got || q{};
This policy prohibits all-whitespace strings constructed by single or double quotes, except for the empty string when it follows the high-precedence "or" or "defined or" operators.
