Re: Can I avoid loops getting the single value from a hash without knowing the key?

> If a hash has only a single value, is there a nice way to get the value without knowing the key and without a foreach loop?

A hash in list context returns just all pairs, so

(undef, $value) = %hash

will do!

The undef syntax just ignores the key if you really don't need it.

Regarding your code .... Sorry tl;dr, please keep it short next time!

HTH! :)
