Maybe we should move (?) out of the arguments list as a means of creating a
partial.
What I realized is that we need a way of signaling partial function
creation. Be it foo(?) or foo(?, ?, ?) or however many ? is added there,
which does not convey any meaning and also doesn't produce any sort of
error!
Say instead of foo(?) we had ?foo().
Since we have named parameters it could help us in providing some of the
arguments and deferring the rest.
For instance:
```
function foo($x, $y, ...$z) {}
?foo(); // causes a partial
?foo(y: '..'); // also causes a partial
```
This way we wouldn't need to worry about the number of ? added to arguments
list.
It may also help in avoiding future PSRs in telling us how many ? we should
put in there :)
