I haven't worked with binary operators in Ruby, but you seem to be on the
right track. Certain you could have an integer, pick the lower bit, divide
be 2. Repeat until integer is zero. For each bit you pick you call yield.
For details on how to implement you own each function, see the PickAxe
book - it has good examples. Sorry for not banging up the code, I just
wanted to say that it would certainly be possible.

There might be some bitvector packages around for Ruby I seem to recall
Robert Feldt did something along those lines.

Indeed doing a Google reveals
