Perl::Critic::Policy::Lax::ProhibitEmptyQuotes::ExceptAsFallback - empty quotes are okay as the fallback on the rhs of ||
version 0.014
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.
This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.
Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.
