Various things in the guile core are done like that, stuff like O_RDWR
for `open'.  The list of symbols Ludovic described is done in the
guile-gtk interface and works nicely too.

If you're entirely in scheme then the ice-9 optargs module to take
keywords is good, especially if you want actual values, not just
yes/no flags.

        (foo #:error-check #t
             #:verbose #f
             ...)
