presumably the parser could handle this syntax if "as" were a keyword.

Not really. The parser is really dumb, it han only handle one alternative starting with a particular token at any point. Since '[' can already start an expression and an expression is a valid statement, anything else also starting with '[', even if it isn't a valid expression, cannot be accepted. You may be thinking of Yacc, which has much more liberal rules.
