This has just been discussed on guile-user - please see the archives
there. (Summary: (i) no (ii) you could use an applicable smob (iii)
description of a roundabout way of achieving the same thing.)

Please do so; however, here is my view of why we don't already have
this (and which may amount to a good reason not to add it - I don't
know).
- The corresponding operation on the Scheme level is achieved much
more elegantly by closure.
- There are ways of achieving this on the C level, even if they are a
little indirect. (See thread in guile-user.)
- The most sensible approach IMO for a Guile-based application is to
do the minimum possible in C for the maximum benefit in Scheme.
Best regards,
Neil
