Re: Abstract Packages

[japhy]

I'll give you merlyn's "don't do my $class = ref($obj) || $obj" advice. Don't do it.

When I need abstract methods, I usually do:

sub some_abstract_method {
  __abstract($_[0], caller);
  # ...
}


sub __abstract {
  my ($thing, $pkg, $file, $line) = @_;
  return if $thing ne __PACKAGE__;
  my $func = (caller 1)[3];
  die "$func is abstract; in $file line $line\n";
}

Same general principle, but I think it's a little cleaner.

For abstract methods, that's practically the same as the code I use. The code I posted was for abstract classes, although I could see how you could always make the constructor abstract, and handle it from there.
