Hello fellow monks! I ran into the following problem and came in search of your advice...

I'm trying to create a 'safe sub' that when called using any of the methods a sub can be called with will still work the same.

So --

my $obj = new PKG; $obj->safe_sub({'foo' => 'bar'}, 'cool'); PKG->safe_sub({'foo' => 'bar'}, 'cool'); PKG::safe_sub({'foo' => 'bar'}, 'cool'); package PKG; &safe_sub({'foo' => 'bar'}, 'cool');
And here's what I've got so far:
package PKG; sub safe_sub { # The next line contains the purpose of my post... shift if ref $_[0] or $_[0] =~ /^PKG/; # The below is just to make sure it's working (or not working :) my ($hash, $string) = @_; print "$hash->{foo}\n$string"; } sub new { bless {}, shift; }
