As mentioned earlier and by others: there are still two options 
(even without a solution for this) that would solve the C ABI 
problem. I'm failing to understand why they wouldn't work:

1) There are only a handful of C functions that would be able to 
receive this tuple (the printf family). Why can't we add an 
overload for them?

2) If (1) isn't an option, wouldn't printf(i"interpolated ...".c) 
work?
