HTTPCore has support for anyio, but we don't document it yet: https://www.python-httpx.org/async/#supported-async-environments

• HTTPX can work with programs that run under anyio, since it'll auto-detect the async environment and use the one set by anyio.
• For maximum consistency, HTTPCore can be told to use anyio internally by passing `backend

Great stuff! I'd love to use this in magic-wormhole.. I only need the DataChannel, though. Any idea how hard it'd be to define a 'feature' for the codecs, so pip install aiortc[video] gets you the dependencies on the codecs, but pip install aiortc[datachannel] does not?

Example of usage:

users = await User.filter(first_name__ilike="c%r")

I know this can be done with startswith and endswith, but there are cases where using the LIKE operator is better:

users = await User.filter(first_name__ilike="j_r%")

This would be used to match Jeremy, Jorge, Jordan...
