Currently you can say:

without warning
function MyFunction(atom this, atom that)
      atom thisother
      DosStuff()
      return 1
end function
with warning

I don't think it's worth it to add extra
qualifiers to the warning system. You can already
turn off warnings for your whole program, or a
file (starting at any point), or around a particular
routine or group of routines.

I wonder if this unused parameter situation
mainly happens when a routine is called via routine_id(),
and is one of many similar routines that are called
with a similar set of parameters.
Perhaps I could omit this warning for routines that are
explicitly named in any routine_id() call.
