Dear, The semantic of short-name option with optional argument is not clear as the comment says:
http://git.savannah.gnu.org/cgit/guile.git/tree/module/srfi/srfi-37.scm#n58 Let consider that the option '-a, --long-a' has an optional argument and '-b, --long-b' another option. Currently, from my tests using SRFI-37: -a X -b # OK (1) -aX -b # OK (2) --long-a -b # OK -a -b # KO (3) The semantic of (3) is ambiguous, obviously. :-) So, it seems that the argument is not optional for the short-name case. One way to resolve such case is to remove the form (1) when the short-name '-a' accepts an optional argument. Does it make sense? Thank you in advance for your wise advice. Best regards, simon
