Why?
I don't see much of any use for namespaces in pure D code,
though I could be surprised.
Because using namespaces is considered good practice in C++.
Those coming from languages with natural namespace support will
see feature with same name and semantics in D code and will
proceed with using it casually, resulting in lot of unidiomatic D
libraries and applications out there.
Namespaces are also much more familiar and simple thing to grasp
compared to original D module system. Providing those will doom D
modules because of path of least resistance - lack of good
practices here makes situation rather bad already, no need to
make it even worse.
Namespaces also don't solve any problem for that can't be already
elegantly solved. We are very reluctant to add new useful
features because of implied implementation, documentation and
learning overhead. Abandoning that principle to add a useless
feature instead is just horrible.
