More code == more bugs. More NPATH = more bugs and harder to test and
to maintain.
In addition, this will result in practice in less generic code,
because one may not need the version of the algorithm without consume
primitives in his/her own code and not code it at all.
Since the performance problem seems mainly to materialize for string
processing code an alternative to this proposal would be to add those
functions only for strings. As far as I heared, most of phobos is
already special cased for string so the maintenance overhead wouldn't be
too big.
It would be nice to think ahead and account things like compressed
streams without extra state in range object. Anyway we are not about to
see them soon.
