Since the question has been raised about understanding \define, etc.
indeed some use remains a bit unclear (to me).

there is a commented blob that implements thinsg like this
\starttext
      \define[2]\whatevera{#1+#2}

      \define[alpha][beta][gamma][delta]\whateverc{#1+#2+#3+#4}
      \whateverc[P][Q]
\stoptext
but it's just an old idea.
I am perhaps a bit bewildered today... but I do not understand the
above. It gets too tricky for me!
that's why it's commented code -)

\define
   [optional-arg-1-default][optional-arg-2-default]...[number of {} args]

but .. not likely to become enabled anyway (was an experiment)
...
Or, maybe, I might like to handle authors:
  \define[2]\Author{\index{#2, #1}#1 #2}
  \Author{Thomas A.}{Schmitz}
But what if I were to type \Author{Aristotle}?
the [] are optional with an optional default
...
\define[one,two,three]\whatever{first: #one second: #two third: #three}
that's not too complex to implement (as mkvi) if there's enough votes 
for it
...

It certainly isn't an urgent need, but having
\define[one,two,three]
wouldn't be absurd, now would it?
