Somewhat related, in Ray Sterner's jhuapl library (other places too, I
think), you can do
;
IDL> hismodule_a, /Help
; or
IDL> dummy=hismodule_b(/Help)
;
but you have to know before-hand that hismodule_a is a procedure and
hismodule_b is a function.

Is there any way to make this work without the user having to know
before-hand?
