(Half the time I want it to, the other > half I don't...) Is there a good discussion of magic, copying magic etc. in the core perl documentation? Or elsewhere for that matter? Any documentation, pointers, general tips, etc. would be greatly appreciated. I was recently bit by overloading magic in the Class::Context generic constructor which the following code illustrates. If you return "another" reference to a scalar which was blessed, instead of the blessed reference, then you loose your magic. I'm trying to keep Class::Contract (which I'm maintaining for Damian) overload friendly... But Perl magic on my map is labelled "there be dragons". package foo; use overload '""' => 'asString'; sub asString { 'Hello World' } package bar; @ISA = qw(foo); sub new { bless \my $key; \$key } package baz; @ISA = qw(foo); sub new { my $ref = \ my $key; bless $ref; $ref } package main; my ($bar, $baz); $bar = bar::->new(); $baz = baz::->new(); print "bar $bar\n"; print "baz $baz\n"; Results In: bar bar=SCALAR(0x1bbfc9c) baz Hello World
