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?
