type checking templates

I hope TypeScript will land this

- https://github.com/microsoft/TypeScript/issues/29432
- https://github.com/microsoft/TypeScript/issues/33304
- https://github.com/microsoft/TypeScript/issues/31422
- https://github.com/microsoft/TypeScript/pull/49552

sooner than later, and I also saw

- https://github.com/developit/htm/issues/73

In the meantime, have there been any other ways to type check `developit/htm`'s tagged template strings? For example any fork of `ts-lit-plugin` or anything else?

The issue names htm tagged template strings and links several TypeScript issues, a TypeScript pull request, and the ts-lit-plugin discussion. Start by reviewing those references to determine whether an existing type-checking approach applies. The payload does not define files, tests, or a completion criterion.
