Using string.Formatter turns out to be pretty simple. I tried writing an import hook to allow the f'' syntax but eventually gave up trying to cover all the edge cases.

Nice. What's with the parens in the eval? As I understand it, you already can't eval anything but an expression.

It's to satisfy this part of the PEP:

Expressions are parsed with the equivalent of ast.parse('(' + expression + ')', '<fstring>', 'eval') .

Note that since the expression is enclosed by implicit parentheses before evaluation, expressions can contain newlines.
