The question is: why do we need to distinguish?
Python doesn't require this. You can not only use either
positional arguments or named ones, you can mix them.
So if you write:
fun f(a:int, b:int) ..
we might think of this as a function taking a record so that
f (a=1, b=2)
works (assuming the argument syntax here can replace struct { ..}
syntax currently requires).
And then, if we allow records to be initialised by tuples:
X (1,2)
then
f (1,2)
is just an initialisation of the argument record by a tuple ..
Of course there is the issue of overloading to consider etc...
