f-string capability in a function

[Skaperen]

could you show a complete and simple example?

ultimately i want a function such that:

send_string(f'{foo} == {bar}')

could be done like this:

send_string(skaplib.fstring('{foo} == {bar}'))

it's a pointless choice if the string is a literal. but if the string is gotten from somewhere else the function could be of value:

send_string(skaplib.fstring(somewhere_else('xyzzy')))

it might get the string from a multi-language message library, as an example.
