Description

It is relatively easy to adapt a closure to a one-method interface. And such conversion should be very useful for implementing functors from within groovy.

syntax can be:

{a->a.name=="a"}

as Predicate

The attached class is a dynamic proxy that implements this adapter functionality. It is currently used in a category class to enable a syntax like "Predicate.impl

{...}

".

Just hook it up to the "as" keyword should make it work.
