What's more important is whether this ideas raises interest or not. I'm not sure myself whether it's a good idea and that's why I posted the idea here.

There are lots of possibilities for overgeneralization here. E.g. most of the examples of the $x"..." syntax are just as easily done using a function call, either passing a string or a few numbers. One danger of new notations is that it could be much harder to find out what it means if you're not familiar with a program. If you see a call to Frobozz(1, 2), it usually isn't hard to find the definition of Frobozz -- at the worst, it's hidden in an "import *", and that's one reason to avoid those. But if you see $f"1 2" in a file, you may have to grep all code that is imported by the program containing that file for calls to sys.register.

You're probably right.
