in reply to Re^2: A "but" operator.
in thread A "but" operator.

Something like?

my Model $T = Ford( color => any( @colors ) ) but 'black';

    I believe you are thinking of "except". </grammar-nazi>

      No, I'm not.

      Anecdotal history suggests that Henry Ford's sales pitch for the Model T was "you can have any color you like; so long as it's black". </history_nazi> :)

      If I understand TimToady's statement of but being a mixin that allows you to contradict (override) early conditions or restraints, the analogy is that you take the guy's order for his model T, and allow him to specify whatever color he wishes; but you then override that by supplying a black one.

        then it is in the meaning of &&?
