It works in this particular case, yes. Just like the example I gave in 
my original case:

eval("f'" + s + "'")

"works" if there are no apostrophes used. And just like

eval("f\"" + s + "\"")

"works" if there are no quotation marks used.

I don't want to have to care about what quotation is used inside the 
string, as long as it could successfully evaluate using the f-string 
grammar.

I have a string. I want to evaluate it as if it were an f-string. I.e., 
there *are* obviously restrictions that apply (namely, the syntax and 
semantics of f-strings), but that's it.

Best,
