cvecs ← ##.fnrefs func                      ⍝ External refs from tradfn ⍵.

Returns a vector of names referenced by function: func. This list is approximate
and should be used only as a guide. It does not, for example, 'see' names refer-
enced by the execute function: ⍎, nor does it compute correctly in all cases the
scope of names within a D function.

Fnrefs attemps to bind namespace references, so that "" and "##.dd" will
each contribute a single item to the result.  However, "(refs #).ee" will gener-
ate three items: 'ref' '#' 'ee'.

See also →externs← which does a better job for dfns but not so well for tradfns.
