Unfortunately that only works with "regular" parameters; you can't do that
with pass-by-reference params because you need to have something passed for
each param to the function. For example, the following won't work:

on test
  put 10 into tVar
  get add10(tVar)
end test

function add10 @pVar1, at pVar2
  add 10 to pVar1
  add 10 to pVar2
end add10

It will error out unless you provide a second "dummy" variable:

on test
  put 10 into tVar
  put 0 into tDummy
  get add10(tVar,tDummy)
end test

And that would be really ugly (among other things)...
