(procedure-property obj 'arity) being the operative part, it gives a list of "(required-count optional-count more?)". "required-count" many arguments required, plus up to "optional-count" further, or if the "more?" flag is #t then an arbitrary number more. I've been using it in my lint program (gratuitous plug). A few funcs defined in scheme code take "(foo bar . rest)" style rather than have an "optional-count", eg. `atan'. http://www.geocities.com/user42_kevin/guile-lint/index.html _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://lists.gnu.org/mailman/listinfo/guile-user
