The reasons to use mir-algorithm instead of std.range,
std.algorithm, std.functional (when applicable):
1. It allows easily construct one and multidimensional random
access ranges. You may compare `bitwise` implementation in
mir-algorithm and Phobos. Mir's version few times smaller and
do not have Phobos bugs like non mutable `front`. See also
`bitpack`.
2. Mir devs are very cary about BetterC
3. Slice is universal, full featured, and multidimensional
random access range. All RARs can be expressed through generic
Slice struct.
4. It is faster to compile and generates less templates bloat.
For example:
slice.map!fun1.map!fun2
is the same as
slice.map!(pipe!(fun1, fun2))
`map` and `pipe` are from mir-algorithm.
It is all good, but I am sure many D programmers, myself
included, would appreciate if shortcomings of Phobos are fixed
instead of having a completely separate package with set of
features that overlap... I understand ndslice was at some point
in the `experimental` package, but again - it would be good if
you improve existing Phobos stuff instead of providing a separate
library that provides better implementation(s).
