If you don't have enough information above to solve the error by yourself (or to understand to which web service the error is related to, if any), please file an issue.

I don't think you should have landed this as there's no tooling support for this...

[bzbarsky]

Hmm. Is the IDL in question actually being ingested by other tools? If so, we need to revert this for now, yes.

[annevk]

Well, yes, Web IDL is written in bikeshed, which does a bunch of processing on it using widlparser. (This is why I think we should have changes for those lined up as well before we approve syntax changes as there tends be quite a bit of confusion afterwards when that's not done.)

[annevk]

And also, the tools scraping specifications for IDL to put it into web-platform-tests are also not updated yet I think.
