I'm not understanding your message. We don't call FORMAT_VALUE on constant 
strings in f"x is {x}" & FORMAT_VALUE doesn't take an argument. Are you saying 
in a hypothetical FORMAT_VALUE where BUILD_STRING takes a set of objects & 
applies formatting to them, thus allowing us to remove FORMAT_VALUE as an 
opcode? That seems like I'm imposing my own internal thoughts on what you're 
saying, but when I don't understand what someone's saying I'm prone to raise my 
own imaginations. Also note that f'{x}' compiles to 'LOAD X, FORMAT_VALUE' so 
there is no join lookup in the last benchmarks I posted

Nitpick about fstrtup2: it assumes compiler_joined_str's len is at least 2. 
Either an assert should be added or the last if-else should be `else if (len == 
1)` instead of a plain `else`
