Yes, very good work, if I didn't say so before.

So do you have a code repository hosted somewhere yet for people to try
this out? Would you like help setting something up? I wonder if
developing it separately for a while might be better than posting a code
dump on the patch tracker. But no harm in doing either or both.

Yes exactly.

No, you are not wrong. Lachlan's assertion was that nested functions are
commonly used in Matlab to implement such callbacks. I can't say wheher
that is true or not, but the scoping behavior with nested functions is
an advantage. With subfunctions the user might have to use global
workspace variables to share state.

I wouldn't consider the lack of handles to nested functions to be a
blocker.

Qt Creator is also available on all of the above operating systems.
