Yes, I think you're right.
For some reason I thought that using reserved words in ways not
permitted by the grammar produced undefined behavior, to support
shells with extensions like the arithmetic "for". But now that I read
more closely, it looks like "function", "[[", "]]", and "select"
produce unspecified behavior but everything else is pretty well
specified. Thanks for clarifying.
