BrowserUK's response is good, I guess, but I want to offer the following because it uses an interesting but rarely used feature of perl.
sub which_obj
{
# examine the calling sub's 'wantarray':
defined( (caller(1))[5] ) ? $_[0]->copy : $_[0]
}
Then you can:
sub foo
{
. . .
my $obj = $self->which_obj;
. . .
}
We're building the house of the future together.
