So you'd want to make sure the value doesn't overflow, but max_value
checking
could be verified in the parser. Again though, not a blocker, I just
think that
would be easier on people. SpiderMonkey outputs some pretty nice
static errors
for a lot of these, but V8 is just saying "Unexpected token ____"
which is not
that great.
Not a blocker but something to think about
Alternatively, we should enable the scanner to give proper error
messages.
