I like the way you think. Can I subscribe to your mailing list?
One thing to point out with the desugar is that it has a bug and most
JS libs have the same but. querySelectorAll allows multiple selectors,
separated by a comma and to do this correctly you need to parse the
selector which of course requires tons of code so no one does this.
Lets fix that by building this into the platform.
