[ahejlsberg]

@DanielRosenwasser I’m pretty sure that comes from #49119 (which incorporated the change from #48366). When checking whether an unconstrained type parameter T is assignable to some type X, we used to check whether {} is assignable to X. We now check whether unknown is assignable to X, and in this case it isn’t because T could be undefined or null. This seems like a very legit error.

It’s nonsense because I didn’t add // @strictNullChecks: true to the repro. But I wonder what change it thinks it picked up on, hah
