  • Now, it has been a while since I messed around with Perl 6, but IIRC it would look something like this:

    sub add ($x, $y) { $x + $y }
    &inc := &add.assuming(x<1>);

    This is actually much closer to what Haskell is doing too, since when you pass less then the expected number of arg to a function in Haskell it will "auto-curry" it for you. It actually does this kind of as a side-effect of being built atop a more pure lambda calculus engine, since in lambda calc functions can only have one argument.
