in reply to Re^2: Hash arrays
in thread Hash arrays

Yes - that looks cleaner, but it is not the equivalent.

Your code overwrites the contents of $family_hash{$key} while the OP's appends.
So, if the $key appears more than once in the input data sequence, all but the last will be clobbered by your code.
