The ambiguity could be quite real.  I have a formula method that just does
preprocessing, then call the default method.  What do the debugger do then?
I've run into situations that I wanted to debug both of them, but not at the
same time.  I just do what Gabor had suggested: debug(namespace:::function).
Works for me.

Best,
Andy
