Perl::Critic::Policy::Lax::ProhibitEmptyQuotes::ExceptAsFallback
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.
