Agreed. Ideally, the standard library would be very uniform in approach. That
makes it easier to learn and use. If it's schizophrenic about it's approach -
especially if it has multiple ways of doing everything - then it's going to be
much harder to learn and use. Everyone would be asking why you'd choose one way
over another and what the differences between them are. It would just cause
confusion.
Ranges are a key element of how Phobos does things in D2. The truth of the
matter is that if you want to effectively use Phobos, you're going to have to use
ranges. If ranges aren't appropriate for a particular module or problem, then
they shouldn't be used, but Phobos is generally being built around using them,
and the more of Phobos which functions in essentially the same way, the easier
it will be to understand, learn, and use.
The old code is indeed available for modules which are going to be
deprecated/removed, and the license is usually Boost, so you're pretty free to
do what you want with it if you prefer it. And there's nothing wrong with
creating your own libraries if you'd prefer. Plenty of folks have done that in
the past.
The standard library needs to be fairly uniform in approach, however, and some
of the current modules are older and don't follow that approach or have
licensing or design issues which were not addressed in the past. Once all of
those modules have been updated, replaced, or removed, Phobos will be more
uniform and its parts will interact better. And over time, it's unlikely that
modules will continue to be deprecated like that. It's happening now because D2
Phobos is still fairly early in its evolution.
