I think concrete means well-defined in this context.

Isn't it also a way to specify an interface only?

Both Perl 6 and Moose allow that, yes.

Perl 6 - the future is here, just unevenly distributed

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.	[reply]

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

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

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.	[reply]

See requires in Role::Tiny/Moose::Role, and Re: Howto create a Moose baseclass/superclass/contract? Moose equivalent of Module::Pluggable? Favorite way to create base/super class?	[reply]
