Alternately, has anyone ever implemented a printf procedure for guile (or

C's printf?

Kawa has a fairly complete implementation of the Common Lisp format routine.
For example: (format "~4,1f" 1.267) => " 1.3". It should be easy enough to also
support the C printf style, as also used by Emacs.

SLib does have a printf implementation, though at least under Kawa it generates the wrong output for your example. (This could be a bug in Kawa, though.) At some I'll get around to ditching the slib version in favor of one using the same code as
the Lisp-style format.
