[MacRuby-devel] Converting Ruby-style method signatures back to Obj-C style

[Laurent Sansonetti]

Hi Gabriel,

There isn't any way to reconstruct the objc selector. We could expose an API, though, if you file a ticket, but I suspect it's not hard to do.

This works great for simple methods that don't have named parameters. However, by the time a call hits method_missing, MacRuby has already converted the method signature to a Ruby-style call.
