I see! I had skimmed through it before but now upon closer inspection it =
does seem to fulfill some of my wishes.

However, it seems the ability to actually use pattern matching as a =
structural interface hinges on whether it will be possible to declare =
patterns as types, which as of now seems to be under consideration. I =
may need to throw my two cents into that RFCs thread.

Thanks for the heads up!
