in thread what means concrete in perlglossary/role - a concrete set of behaviors?

Maybe concrete is also meant as the opposite of abstract, which would somewhat run counter to the idea of "interface without implementation". But I don't follow Perl6 and the various incarnations of the M* modules and theories behind them.

    Am I missing something ... the glossary says "interface without inheritance." Not sure where you're getting "interface without implementation."

    -derby

      Yeah - so it doesn't even run counter to that.

      I took it to mean:

      • abstract : Interface without implementation
      • normal : Interface, implementation, and inheritance if you feel like it
      • concrete : Implementation in stone, no inheritance allowed.
