in thread Isn't that nice?

It's just currying. The syntax is unique to perl, but the semantics are reasonably common in functional programming languages. The 'new' thing about perl 6's 'assuming' operator is that, according to Damian, it doesn't actually create a new function, but that's not really going to be user visible.
