Inline widgets for variable hinting

[ItsMeBrianD]

We should have some sort of type hinting for places that have "implied" names.

For example when writing noise:

N := Noise { 1 [ 1 2 3 ] }

We would want to have some sort of inlay hinting for _firstOctave_ = 1 _additionalOctaves_ = [ 1 2 3 ] to make it easier to see what's happening under the hood
