What is Perl doing with this argument to push in this case?
- by Morinar
I just saw some code in our code base (and it's OLD code, as in Perl 3 or Perl 4 days) that looks like this (I'm simplifying greatly):
my @array;
push( array, $some_scalar );
Notice that the array in the push() doesn't have an @. I would assume that the code behind push knows that the first argument is supposed to be array so grabs the array from the array typeglob. Is that more or less it? If Perl is able to do that without problem, why would you need to include the @ at all?
