I don't know if we ready to implement something like that, but technically I
would expect DOMStringList to extends List<String> interface, but be a separate
interface and implementation on its own.  The unpleasant part is we should
ideally accept List<String> as input argument---once again I hate IDLs---they
should distinguish those cases.

Maybe we should provide such overrides in our supplementals, wdyt?

Or make generator uglier and allow more generic types as arguments, wdyt?

I'm piggybacking on sequences support that we have in our generator. See
dart.idl for the list of classes that currently implement List<T>.
I think List<String> as input argument should work as we have custom toNative.
Am I missing something?
