Function application signature help - improvements list #10957
Description
This tracks improvements to the signature help feature for function applications.
- Tooltip disappears when typing out arguments in a function application
This one is tricky with the current implementation. We can either:
- Keep the tooltip up when typing out arguments to a function application
- Keep the tooltip up when typing out arguments in a method call
The latter has always worked, so it's currently implemented to do that. But it'll be more work to figure out how to do both.
- Still triggers unexpectedly inside of a parenthesized context
As of #10954 this should be improved a lot, since it covers parenthesized contexts that have a lambda. But it can still trigger in cases like this:
To address this, we'll need to figure out a way to generalize the parenthesized case for TryRangeOfFunctionOrMethodBeingApplied.
