Named parsers would be wonderful, especially if expectations also had access to the scope 😅

👍 At least superficially, this seems similar to the named codec support in scodec.

@ val c = int8.withContext("x") ~ (ignore(8) ~ constant(0).withContext("z")).withContext("y")
c: Codec[(Int, (Unit, Unit))] = (x(8-bit signed integer), y((ignore(8 bits), z(constant(BitVector(8 bits, 0x00))))))

@ c.decode(hex"000011".bits)
res2: Attempt[DecodeResult[(Int, (Unit, Unit))]] = Failure(General("expected constant BitVector(8 bits, 0x00) but got BitVector(8 bits, 0x11)", List("y", "z")))

from cats-parse.
