Re^2: Throw compilation error(or warning) if duplicate keys are present in hash

[I_love_perl]

Hi Ikegami, Thanks for your quick response.

I've tried using Perl::Critic (http://perlcritic.com/), but it is not throwing up any warning with respect to the re-occurrence of the hash key. Correct me if I'm doing something wrong in using Perl::Critic

I didn't say a rule already existed to check this. Quite the opposite, I assumed there wasn't one and told you you'd have to actually write the rule.

A policy for this now exists, but you'll need to install Perl::Critic::Pulp.

See http://search.cpan.org/dist/Perl-Critic-Pulp/lib/Perl/Critic/Policy/ValuesAndExpressions/ProhibitDuplicateHashKeys.pm
