Python’s new t-strings

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.

Assuming you also need to format non-values in the SQL (e.g. column names), how does the `execute` function is supposed to make the difference between stuff that should be formatted in the string vs a parametrized value?

Same as currently: the library provides some sort of `Identifier` wrapper you can apply to those.

Fair enough. It would be nice if Python allowed to customize the formatting options after `:`

This way you could encode such identifier directly in the t-string variable rather than with some "out-of-band" logic.
