I'm willing to do any or all of those things! defineAnonymousClass is
still not a publicly-accessible API, though, which is why I have not
used it up to now.

We don't have any plans to baseline on 11 yet, but could possibly be convinced.

I think you understand my use case pretty well... maybe you can point
me at an example of what you think would be the "best" way, assuming
we moved our baseline to 11?
