Once upon a time – in August this year – I started a (somewhat badly titled) thread about improving the f-string grammar: <a target="_blank" href="https://mail.python.org/pipermail/python-ideas/2016-August/041727.html">https://mail.python.org/pipermail/python-ideas/2016-August/041727.html</a> Luckily it resulted in an interim grammar change that invalidated a misleading property of the original grammar: To the rejoicing of syntax highlighters and humans everywhere, it’s no longer possible to escape syntactically relevant characters such as the f-string braces: f'\x7bvariable}' Now I created a PEP that makes f-strings work just like every other languages’ string interpolation; enabling arbitrary nesting of python expressions in the expression parts of f-strings: <a target="_blank" href="https://github.com/python/peps/blob/master/pep-0536.txt">https://github.com/python/peps/blob/master/pep-0536.txt</a> All I want for christmas is your help: Please tell me how to improve wording, structure, or clarity of my PEP’s message (ideally via PR to <a target="_blank" href="https://github.com/flying-sheep/peps">https://github.com/flying-sheep/peps</a>) I fear going forward I will also need guidance for the implementation part, as my only close-to-the-metal experiences are dabbling in C++, and the higher-level language Rust. Thank you and happy holidays!
