Re^4: Throw compilation error(or warning) if duplicate keys are present in hash

[I_love_perl]

Hi Ronald

Yes. Absolutely we can write a piece of code to check for the existence of duplicate keys in a hash or array. But I felt like it should be present in some perl program check utilities (like use strict, use warnings).

As I don't know if this facility is available in perl I posted this query to know if there some package(or pragma) available for this kind of checks.
