For what it's worth, you can also get 90% of the way there with:
f <- glue::glue
f("if you squint, this is a Python f-string")
Having this in an add-on package also makes it much easier to change
in response to user feedback; R packages have more freedom to make
backwards-incompatible
I don't think a custom type alone would work, because users would expect to use
such string anywhere a regular string can be used, and that's where the
problems start - the evaluation would have to happen at a point where it is not
expected since we can assume today that CHAR() doesn't
