#4671 proposed adding a lot of new symbolic constant features to a helper somewhere in Twisted. This is for the kind of symbolic constant that has a value like a bit in a bitvector and which can be combined from other constants which are part of the same logical group, using all of the traditional bitwise operations.
This would be useful in conch, because SSH uses lots of bitvector-style constants.
