29c1e9a0d4 Document the difference between expressions and statements [ci skip] 
In the grammar, all expressions are statements, but not all
statements are expressions.  Some parts of the grammar accept
expressions and not other types of statements, which causes
similar looking code to parse differently due to operator
precedence.

Mostly from Dan0042 (Daniel DeLorme).

Fixes [Bug #16092]
