Looks like you're introducing a change to the public API surface area. If this includes breaking changes, please document them on our wiki's API Breaking Changes page.

Also, please make sure @DanielRosenwasser and @RyanCavanaugh are aware of the changes, just as a heads up.

These are the generator types: for 5.5, I had to use any in these cases since unknown is not assignable to undefined (and the inferred TNext type in these cases is undefined

Pretty hard to review the whole thing because the diff is so big, but I do wonder if we should even bother doing this for harness/testRunner given those don't actually have a public API...

In general though I do think we should try and name some of the types introduced here. That and there are some really unfortunate losses of inference here :(

these are the places where any shows up (not counting workarounds for generators). there could be better ways to type them.
