Either you should not be using #map above or assign the result of #map 
to functs.  A #map without using the result is pretty useless.

But definitively #scan is the right tool for the job.  If only printing 
of function names and arguments is interesting that could be done inside 
the #scan body as well avoiding a second pass.

Kind regards
