This enables the test suite to build with the -property switch enabled.
std.cpuid: vendor()/processor() have not been converted to properties in accordance to core.cpuid.
std.xml: Element.text() cannot be a property due to the optional parameter.
This patch also removes many other workarounds in the function (2562, 2564, 2569).
Note that the return type has been changed from char[] to string, but since this
function is intended for mixin(), it should not cause many trouble.
* 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.
- Tuple members are now accessible with the syntax a[0], a[1] etc.
- Eliminated an internal union (see bug 4421 and 4846). Re-implemented named members with alias.
- Worked around bug 4424. Got opAssign back.
- Made Tuple.slice!(from, to) to preserve field names if any.
- Added isTuple!(T) template.
- Removed the 'default constructor' that is never called.
- Changed Tuple.toString() to use formattedWrite() instead of the `static if (is(to!string...))` thingy.
