* Eliminate well-known symbols in the checker: 2021 edition
* Actually update the lib text to say unique symbol, too (this is unneeded with compat code in place, but this makes goto-def make more sense)
* Add test showing mismatched symbol constructor type interop
* Add more test cases for some other related issues this fixes
* Revert computed name change
* Style comments
* Signature help: support non-trailing rest parameters
In signature help, the first rest parameter will always be the *last*
'current' parameter (disregarding types). Previously, the signature help
current-parameter highlight was only correct for trailing rest
parameters. However, with tuple types, you can now create non-trailing
rest parameters. This PR now correctly highlights non-trailing rest
parameters as the last 'current' parameter.
For example, `names` should be the current parameter in all the calls
below:
```ts
declare function loading(...args: [...names: string[], allCaps: boolean, extra: boolean]): void;
leading(/**/
leading('one', /**/
leading('one', 'two', /**/
```
And, because signature help doesn't do real overload resolution, `names`
is also the current parameter for other calls:
```ts
leading(1, 2, 3, 'ill-typed', /**/
leading('fine', true, /**/
```
* Change 'variadic' to 'rest'
* fix missed rename
* use single, original tuple instead
* Revert "use single, original tuple instead"
This reverts commit f0896f32ea.
* Improve sig help of trailing rest too
1. Trailing rest keeps highlight at end instead of going off the end.
2. Non-trailing rest disable highlight entirely (by putting the index
one past the end).
