2^64 -1 cannot be represented

[jrakow]

The highest u64 value (18446744073709551615) cannot be represented with the current Token::IntegerLiteral(i64).

One would probably need SignedIntegerLiteral(i64) as well as UnsignedIntegerLiteral(u64).
Or you could use on of the 128 bit types.

Do you have any preference to the two fixes?

[jrakow]

I think the two variant version matches the grammar most closely.
It is also extensible, should WebIDL ever allow 128 bit tokens.

@jrakow Can you confirm the fix is what you want before I push a new version?

[jrakow]

This uses u64 as fallback and all the values in the spec can be represented now.
So yeah, looks good to me.

Version 0.7.0 should have the fix. Thanks for the report.
