Thanks for the detailed explanation and example. Yes, that may well be
a reasonable highlighting scheme.

I'd still object to reusing single quotes in the example given,
though, as it would be confusing if printed, or in email, etc. And as
a general principle, "needs syntax highlighting to be readable" is a
problem to me. So I stand by my statement that as a style rule,
f-strings should be written to work identically regardless of whether
this proposal is implemented or not.
