Type imports, with runtime support

[tmk (Thomas Kehrenberg)]

There is a new PEP about it:

PEP 810: Explicit lazy imports

Hi everyone, We are very exited to share with you PEP 810: Explicit lazy imports: We’re proposing an opt-in lazy import syntax that defers module loading until first use, aiming for faster startup, lower memory, and clear semantics with zero overhead when not used. We worked hard to balance user value, an elegant implementation, and predictable behavior, and we’ve included alternative implementation paths where trade-offs are worth discussing. Not only do we believe this is import…

Looks like this will also work for typing-only imports.
