    While that looks nice, be very careful to not use a map that returns multiple entries per input with a long list before 5.6.1 is out. Unfortunately it currently scales quadratically: 
    %hash = map { $_, $_ } 1..20_000;

    If that doesn't make you a believer, s/20/100/ and try again.

    This applies to all versions of Perl with map until the upcoming 5.6.1.
