Yes, that's good, and you can count me as a reviewer.  — John

P.S. One could also get rid of the LF.customized field by stuffing both that value and the original LF in the transformCache (as a 2-array), but that's overkill.

P.P.S. A possible generalization to the LF.customized field would be an optional list of type, value, and/or structure constraints for one or more arguments to the LF.  Then we could (a) customize on additional arguments if we thought that were useful, and/or (b) produce semi-custom code that could be shared by more than one MH, if we thought there was an interesting equivalence class of MHs to speed up with common code.
