std.algorithm: defined move with one argument; levenshtein distance generalized to with all forward ranges; take now has swapped arguments
std.array: empty for arrays is now a @property; front and back for a string and wstring automatically decodes the first/last character; popFront, popBack for string and wstring obey the UTF stride
std.conv: changed the default array formatting from "[a, b, c]" to "a b c"
std.range: swapped order of arguments in take
std.stdio: added readln template
std.variant: now works with statically-sized arrays and const data
std.traits: added isNarrowString
* Changed some declarations from explicit to auto.
* Changed "mkdir --parents" in Makefile to "mkdir -p" since OSX doesn't support the long version.
* REMAINING ISSUE: The "ln -sf" for installing the libraries at the end will fail if the DMD installation point is not owned by the user performing the build. A "sudo ln..." fixes this, but it still may not be ideal to have a system-level link to a user-level file. This should probably simply be copied instead. Also, this copy should perhaps be done manually or in an "install" step, since a user may want to build Phobos and test it out without affecting other users.
* Transformed std.c.linux.* into wrappers around core.sys.posix modules where appropriate.
* Added std.c.osx as the OSX equivalent of std.c.linux.
* Added std.c.osx.socket for OSX-specific socket declarations not covered by the Posix spec.
* Altered all makefiles to zip, etc, the new std.c.osx package.
* Removed gcstats. Garbage collector statistics will be avaialable in durintime's 'memory' module.
* Removed object.d. This module is replaced by the object.d provided by druntime.
* Removed std.array. To trap an array bounds error, import 'exception' from druntime and catch ArrayBoundsException.
* Removed std.asserterror. To trap an asertion failure, import 'exception' from druntime and catch AssertException.
* Removed std.gc. To interact with the garbage collector, import 'memory' from druntime.
* Removed std.hiddenfunc. No equivalent exception is currently exposed by druntime, but if one is exposed it will be called HiddenFuncException and be declared in 'exception'.
* Removed std.moduleinit. druntime declares ModuleInfo in object.d, so it is implicitly availble without importing.
* Removed std.outofmemory. To trap an out of memory error, import 'exception' from druntime and catch OutOfMemoryException.
* Removed std.switcherr. To trap a switch error, import 'exception' from druntime and catch SwitchException.
* Removed std.synchro. This functionality will exist within druintime.
* Removed std.thread. A Thread class is available within druntime's 'thread' module. An interface comparison will be provided separately.
* Removed std.typeinfo. The classes defined in this package are for runtime use and should not be visible to the user.
The prior version of Phobos has been archived in tags/phobos-2.019 if needed.
