Yes, it works, but it doesn't gain anything from it, which is what I

Then what you have said was useless.
No it isn't. The point Pelle was making is that there are three use
cases for parameter passed arrays:
1. read-only (corresponds to const)
2. read/write + resizing/reallocation (corresponds to ref)
3. read/write, no resizing (corresponds to no modifier)
With (1) and (2), if I see those modifiers in the signature, I can
deduce the use of the array.
With (3), I can't really tell from the signature if the programmer meant
that use case or forgot something, but the case is valuable enough that
it should be enforceable.
With associative arrays, case (3) is rare (is it even possible?) to the
point that it can drop out of consideration.
