Hi!
I decided to take a look at how one can parse command line arguments in
Guile and was looking for something like argparse in Python. It seems
that (use-modules (ice-9 getopt-long)) does the job, except that I hit
one problem and don't know what the mistake I am making is. It seems to
be connected to the usage of `predicate` in my code.
You probably want to use quasi-quote + unquote:
`((version ... (predicate ,string-exact-integer?))))
I believe the module (srfi srfi-37), args-fold, is now recommended over
getopt-long.
