Incidentally, it's on my list for this week - and less work is always good. ;-) Even if, in this case, it leads to disappointment. I agree with you in that opening up the MH API like this will introduce several trapdoors and additional complication.

Hi Michael.  See previous message.  It looks like (in most cases, mostly) the burden can be put back on the bytecode generators, like Groovy.

In a couple of cases we might want to add API for these use cases:

1. The workarounds are so complex and error-prone that a convenience function is needed.  (As with PICs, etc., requires a matured notion of what the convenience should be.)

2. We might still need some sort of multi-way super.<init> call, but I think there are bytecode-level workarounds for this also, that verify today.  (The multi-way super comes is visible in the "no can do!" comment of my POC code.)
