I nust saw the #python pep750 and I think an addition could be to have a string like t"hello {{world}}" resolve to `templatelib.Template(["hello ", templatelib.Interpolation(None, "world")])`. The syntax is meant to mirror django. The idea is to have an easy way to use arbitrary interpolation token that can be replaced later from a context. The same could be done with t"hello {"world"}" and use the value instead of the expr of the interpolation but I think the double curly are easier to read

I'm posting that here because I have no idea how to suggest addition to a PEP, I have no idea if it's a minor addition (the syntax looks different from anything from f-string which might be major addition territory, while a t"hello {world@}" might reuse the same mechanism as the debug specifier, making it easier to implement, with @ mirroring makefile do not echo this line) and honestly I don't care enough about it to create an account or support the idea beyond making it float out there
