Who said that Perl doesn't have a clean syntax? :)

    It works here on 5.14.1. Very cool.

    What I want to know, is how did you come up with this? What goes on in your mind? :-)

    Hmm, doesn't seem to work on Perl 5.12:

    Type of arg 1 to push must be array (not string eq) at + line 12, near "gethostent and" Type of arg 1 to unshift must be array (not quoted execution (``, qx)) + at line 17, near "pos xor" Type of arg 1 to shift must be array (not umask) at li +ne 17, near "pos xor" Type of arg 1 to splice must be array (not shift) at l +ine 17, near "pos xor" Type of arg 1 to pop must be array (not wantarray) at +line 22, near "wantarray and" Type of arg 1 to shift must be array (not kill) at lin +e 22, near "wantarray and" Type of arg 1 to unshift must be array (not shift) at +line 22, near "wantarray and" Type of arg 1 to splice must be array (not unshift) at + line 22, near "wantarray and" Execution of aborted due to compilation errors.

    Very impressive. It is a shame it only works on the most recent perl releases, presumably because of the new feature where functions that take arrays etc can also take references to those types.
