Demangle D mangled names.
Walter Bright, Thomas Kühne, Frits van Bommel

Source std/demangle.d

pure nothrow @safe string demangle(string name);
Demangle D mangled names.
string name the mangled name
A string. If it is not a D mangled name, it returns its argument name.
// int b in module a
writeln(demangle("_D1a1bi")); // "int a.b"
// char array foo in module test
writeln(demangle("_D4test3fooAa")); // "char[]"
This program reads standard in and writes it to standard out, pretty-printing any found D mangled names.
