Matt Trout's Devel::Declare, which is used by Method::Signatures and friends are able to do quite scary things without resorting to source filters. IIRC one of the primary motivations was to be able to test and experiment new languages features in a way backportable to older perls, without to have to patch the core. I think that the syntax of Method::Signatures is an excellent ground on which to base a core implementation.Thread Previous | Thread Next
