However it can also enable all sorts of ugly practices. For example, poor man's symbolic references...
use strict; my $red = '#ff0000'; my $green = '#00ff00'; my $blue = '#0000ff'; my $colour = 'green'; my $hex = eval "\$$colour"; # symbolic reference print "$hex\n";
When many newcomers turn to stringy eval, it's often because they're unaware of a better solution to their problem.
This is my problem with Perl::Critic. It takes a generally good guideline (stringy eval is often a bad idea; investigate other options first) and turns it into a concrete rule.
Yes, of course there's no critic comments but I don't really want to litter those around my code like rat droppings. (no strict and no warnings are already enough of an eyesore.)
