You're right, close already implies const.

As for adding keywords: We could consider "soft" keywords (e.g. emitting "keyword-or-name" tokens and leaving the final decision to the parser), though I'm not sure whether that might introduce ambiguities.

Changing the syntax will break compatibility either way. But since the breakage is purely syntactical, this could be fixed automatically.

If there's going to be a change, this is the way to go.  Although added-keyword and breaking compatibility might be a drawback.

Doesn't `close` already imply `const`?
