Details

In bug 1988248, Jeff found a case in the wild where the Proxy apply hook was performance-sensitive. While investigating that, I prototyped a patch that supports calling methods on proxies that don't have an apply/construct hook. Initial results show that it's about 8x faster than going through all the C++ proxy gunk.

It needs some tests before it is ready to land.
