a while back I wrote a piece of code that was basically a generic
equals method for objects. I'm wondering if I patched moose to give
objects this functionality if it'd be accepted?
basically it was something like
refaddr ==
blessed?
isa?
...
and a few more checks, the external interface was
1 classes are equivalent
0 classes are definitely not equivalent
undef superclass/unmodifed method says it's not equivalent but it
still could be determined to be equal by a subclass.
this method would make it easier to do simple equals methods on things
like entities, for example:
override equals => sub {
my ( $self, $obj ) = @_;
my $ret = super();
if ( ! defined $ret ) {
return 1 if $self->id == $obj->id;
}
else {
return $ret;
}
return undef;
};
and of course you could just completely redefine it.
