In the "Composition with other prefixes" section, I don't like how
f'...' uses {} syntax but fb'...' uses % syntax.

In the "Environment Access" section, I would've expected f'Home folder: 
${HOME}' to do ''.join('Home folder: $', HOME.__format__('')).

BTW, in the "Reference Implementation(s)" section, it's "its work", not
"it's work".
