D programming language (dlang) symbol name demangler for C++
```cpp
std::cout <<
demangle_d::demangle("_D3std5stdio__T8writeflnTaTiZQoFNfxAaiZv")
<< std::endl;
// Will print: void std.stdio.writefln!(char, int)(const char[],
int) @safe
```
Goals
* Easy of integration into any C++ codebase
* Flexible
* Code simplicity following the spec closely in shape
Status: Alpha.
The principal motivation was to have a clean-room, from scratch
implementation, that can be easily used in various contexts. The
code base is simple, and can be easily ported to other languages,
and environment (i.e. kernel space).
Once this is polished down, I will be pushing this demangler to
be integrated into few 3rd party code bases, for example Valgrind
/ massif, heapcheak, pprof, tcmalloc, Linux perf, etc.
