Hmm. I was thinking along the gnulib mechanism which provides
drop-ins for many system functions.

That’s fine, but if it’s going to be a prox

What about emulating `scm_is_exact_integer', either in Scheme or in
C++? This should make transition to Guile-2 simple.

scm_is_integer is not nearly a sufficient prerequisite for calling
scm_to_int (well, of course there are size limits but that's not what I
am talking about). Try
{ \repeat unfold #2.0 c'1 }
which crashes in some strange place. Use #2 instead and it works (of
course), use #2.5 and it fails in
