OK, fair enough.
I think I’ve already sufficiently distracted you, and I’m fine with you
committing the patch (and after all, we’re talking of one C function.)

It’s become our motto! :-)
I don’t want to block improvements to the C interface, and I agree that
this convenient C interface has been one of Guile’s strengths, which we
should keep. But I wouldn’t want them to block improvements to the
Scheme implementation.
First, maintaining the compatibility of C functions can be hard, at
least harder than maintaining a Scheme interface because Scheme has
optional arguments and so on. Second, the C interface can expose
details that hinder improvements of the Scheme implementation—e.g.,
‘scm_values’, dynamic-winds, etc.
Thanks,
Ludo’.
