This seems redundant here.

Fair enough. I'll need to remember to add it back once browsers actually add support for this async iterator, and it actually ends up in the generated types. 😛

Hmmmmm. That said, this is the only needed manual data and we know it will eventually come, so maybe we can keep this 👀

I'm not a fan of having extra files, but I guess we need it 🥲

Thanks! LGTM. |

Add support for
async iterabledeclarations per Web IDL, and emit them as.asynciterable.d.tsflavors. This is a first step towards microsoft/TypeScript#29867.At the time of writing, only
FileSystemDirectoryHandle's async iterator is supported by two browser engines (Chrome and Safari).ReadableStream's async iterator is not implemented anywhere yet, and gets correctly filtered out bygetRemovalData().Fixes part of #1393.
