Description
From Hannes.

Issue 1 just adds compile time. Issue 2 should be investigated.

1) I think the NodeVisitor in ApplySpecialization#hasApplies will enter into nested functions. Shouldn't it just look at the current function?

2) I wonder how hot the TransformFailedException constructor may get. Should we worry about string concatenation there?
Comments
Verified that after not descending into nested functions, --log=apply2call shows the same functions are still being transformed.

I wouldn't worry about the TransformFailedExceptions. They only come into play if checkValidTransform() is invoked, and that only happens if hasApplies() returned true. It is never invoked for functions that don't have an apply in them.
