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.

Now instead of being explicit all it takes is someone unfamiliar with t strings (which will be almost everyone - still few know about f strings and their formatting capabilities) to use an f instead and you are in for a bad time.

Any sane library will just error when you pass a string to a function that expects a template though. And that library will have types too so your IDE tells you before you get that far.

This would break backwardcompatibility pretty hard. In many cases it may not be worth it.
