All things considered, this is pretty cool. Basically, this replaces

    db.execute("QUERY WHERE name = ?", (name,))
with

    db.execute(t"QUERY WHERE name = {name}")
Does the benefit from this syntactic sugar outweigh the added complexity of a new language feature? I think it does in this case for two reasons:

1. Allowing library developers to do whatever they want with {} expansions is a good thing, and will probably spawn some good uses.

2. Generalizing template syntax across a language, so that all libraries solve this problem in the same way, is probably a good thing.

One thing it misses is compile-time checks for e.g. the format spec.

Do t-strings miss something that f-strings provides for format_spec etc.?

FWIW, format_spec is available in the template structure, so the function writer could at least do a runtime check.
