I can't: no one can because the SQL standard is not available online.
But you can look at various proxies, for example here:

right, well, I meant hypothetically; I was following along with your
thinking and extending inline code blocks to be able to be used in any
place where a function is allowed.  Specifically I was wondering if
there are technical limitations that keep them limited to CTE usage
(as is the case with data modifying WITH).
