I would like to be able to return the argument list of a Scheme function, say as a list of symbols. So, for example, in the case of grob-interpret-markup, I would like to retrieve '(grob text). There are a number of functions for determining information about procedures listed here: http://www.gnu.org/software/guile/docs/docs-1.8/guile-ref/Procedure-Properties.html
but, I see nothing to return an argument list. How would I go about doing this?
