import std.demangle, std.stdio;

void main() {
    auto a = (float x, char y) { return 0; };
    auto b = [ 1, 2, 3 ];
    auto c = 3.5;

    writeln(demangle(a.mangleof));
    writeln(demangle(b.mangleof));
    writeln(demangle(c.mangleof));
    writeln(demangle("_D3std4math3cosFNaNbeZe"));
    writeln(demangle("_D3std3utf6toUTF8FG4awZAa"));
    writeln(demangle("_D3std6string7sformatFAaYAa"));
}

output:

DFfaZi
Ai
d
_D3std4math3cosFNaNbeZe
char[] std.utf.toUTF8(char[4], dchar)
char[] std.string.sformat(char[], ...)

So it does unmangle some of the symbols, but it's very limited currently.
