Inspect - identify when position is left hand side of assignment

[mattmasson]

We shouldn't return intellisense suggestions when we're on the left hand side of an assignment (i.e. providing a variable name). Ex:

let a = 1, |
let a = 1, bin|

Ideally, the inspection result would provide a boolean flag that the intellisense code would use to determine that no suggestions should be returned in these cases.

@JordanBoltonMN - thoughts/suggestions on how to best implement this? Would I check if the closest node is a Constant(,), but not a parameter for an invoke expression?

Maybe there is a parser context/state that expects an identifier declaration?

I see a few scenarios considering the inspection finds the closest leaf node to the left of the cursor, then travels upwards through its parents:

• If you reach a GeneralizedIdentifierPairedExpression, then you must be in a RecordExpression. When in a record expression you either are or are not on the key
• If you reach a GeneralizedIdentifierPairedAnyLiteral, then you must be in a RecordLIteral. When in a record literal you either are or are not on the key.
• If you reach a LetExpression, then you may be in a LetExpression. First check if the parent is a LetExpression, then check if you are either are or are not on the key.
