Re: How Do I pass a hash to a subroutine?

[thephpguy]

MeowChow's code for passing by reference is VERY inefficient unless you actually want a copy of the Hash. (Why pass by ref if you want a copy?)

  mysub(\%hash);

  sub mysub {

    my $paramhash = $_[0];
  }

With the above code any modification will affect the original hash.
