Currently, the regular expression grammar rules in [re.grammar] are formatted with crude codeblocks:
In the ECMA standard itself, rules are typeset like this:
So as an experiment, I tried mimicking that typesetting. Result:
Personally, I think it looks nicer than the crude codeblocks, and matching the upstream ECMAScript re grammar typesetting more closely is a nice bonus. What do you think? :)
(Incidentally, this also benefits cxxdraft-htmlgen, because it reduces the amount of non-C++ code in codeblocks.)
