Re^2: Modify a hash via its reference

No need for the "()" around a single my variable declaration

This is true in most situations but not all. From the OP's code:

  my ( $Ref_to_Hash ) = @_;

In this style of parameter initialization, the parentheses are in fact required. Otherwise $Ref_to_Hash will be assigned the number of arguments, not the value of the first one.

I stand corrected (which is why I love this place). Thanks, I learned something.
