Concretely, we should consider upright teletype for these placeholders: P and Z (types), and e and h (objects). p, a, o, await-ready, await-suspend, and await-resume are all macros for a specific syntactic construct, so italics for those seems appropriate.

It's not clear what to do with s in /5.1, which is "a value". But then we talk about a call "s.resume()", which doesn't make sense, since you can't make a call on a value. I think s should actually be the await-suspend expression itself:

If the await-suspend expression has type std::coroutine_handle<Z>, the coroutine referred to by that handle is resumed as if by calling await-suspend.resume().

Fitting that into the surrounding bullet may require some massaging of the text.

e and h are nebulous -- e is an lvalue, and h should probably be a prvalue, so they're both syntax-macro-esque.

Waiting for #2770.
