Remove use of deprecated typedef from phobos. This mostly consists of changing typedef to alias, and disabling unittests that require typedef. One change to std.registry is needed to work around a bug in typedef (6571).
The two templates has same purpose, but bit different behaviors.
implicitlyConverts(S, T) has following semantics:
is(S : T) and allow initializer conversion (T t = s; -> T t = T(s);)
Including initializer conversion is inconvenience for my to!() improvement in after commits, so replace it.
* Made emplace faster and replaced calls to it to also make them faster.
* Replaced phobos.d in posix.mak with index.d.
* Added version=StdDdoc to documentation build in posix.mak, and replaced uses of D_Ddoc with it.
* Improved documentation target in posix.mak (target dir automatically created).
* Added nice documentation table and cheat sheet at the top of std.algorithm.
* Replaced a few helper structs in std.range and std.algorithm with local structs, which simplify matters a fair amount.
* Added more constraints to functions in std.algorithm (still work in progress).
* Improved error message in std.algorithm.sort in case of failure to sort.
* std.random.dice(1, 10) now works (no need for array notation std.random.dice([1, 10])).
* Fixed documentation bugs and insufficiencies in std.range (still more to do).
* Improved speed of walkLength.
* Simplified retro.
* Simplified and optimized stride. Also folded stride(stride(r, a), b) into stride(r, a * b).
* Added roundRobin to std.range, which as a perk simplified radial.
* Added takeOne and takeNone to std.range.
* Added unsigned to std.traits.
This function came from std.date.
But now, benchmark returns Ticks[N] and don't use result argument.
I removed need to use GC for by doing it in this way.
Added unittests for regression bug 4312 (caused by bug 4333). This regression bug is just workarounded, not fixed, so I don't mark it as fixed. The bug 4312 will be closed when compiler bug 4217 or 4333 is fixed (these are blockers against this regression 4312).
Made some templates to print error message on failure, rather than just failing instantiation.
