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