But first there's the task of identifying that the name matches a BIF in
the first place. That's why I was looking for a runtime object that
might list them.
I wasn't looking for this for practical application at all, but I
imagine using it in a debugging routine, for instance. A single routine
could have a long list of labels at the top to intercept calls to
various external routines of all kinds:
MyExec: -- another program
MyRoutine: -- a named routine
ReVerse: -- a built-in function
Trace ?R
Say 'Calling' .context~name
-- really might want all args here, which gets messy:
Interpret "Call '".context~name"'" Arg(1)
Say 'And now back to our show . . .'
If Symbol('RESULT') = 'VAR' Then Return result
Else return
¬R
