This is a nice idea. The way Racket does it is to make
with-output-to-string cooperate with system:
(with-output-to-string (lambda () (system "date")))
but a quick check shows that Guile does not yet have such cooperation in
place. Would that be a good place to start looking?

'system' or 'system*' but that might be capable of capturing the output
of the program that's being called.
While this is something that can be solved with a simple 'open-pipe*'
wrapper, the pattern seems relatively

Hi,
In an interesting (or perhaps maddening) inconsistency,
'with-output-to-port' captures stdout from system* here
(call-with-output-file "/tmp/test.log"
(lambda (port)
(with-output-to-port
port
(lambda ()
(system* "mktemp" "-d")
but 'with-output-to-string' does
