If you treat statement as
EXPR;
(yes, semicolon INCLUDED) or
if (EXPR) BLOCK
then you won't have any problems defining where semicolons go.
A statement is an expression followed by a semicolon, or an if, or a while,
or a naked block, or something in that class.
That clearly explains why
EXPR if EXPR;
is a statement, not an EXPR, so we can't use it recursively.
The only oddness is that a closing brace acts as if it is semicolon-brace
if needed. That way { EXPR; EXPR; EXPR } still parses, because
it acts like you wrote { EXPR; EXPR; EXPR; }.
This seems to be the most natural approach. Define statement as
expression followed by semicolon. Don't try to take the Pascal approach
of "semicolon is statement separator". Take the *C* approach.
