The statement expression itself is not allowed just at places where an ordinary statement would stand. As with other expressions, this is only facilitated via the expression_statement rule that adds a semicolon after the expression. The reason why this bug was not discovered is probably because the code generator also drops the parentheses around the statement expression, turning it into a compound statement. This commit fixes that by removing the faulty rule extension, introducing a CoumpoundExpression class, and making sure the parentheses are added when an object of this type is discovered during code generation.
