I remember names like _add. Is that a Windows thing?

A number of functions are implemented as manually-mangled names with preprocessor macros that forward to them. It's weird, but it happens.

But he says `The fuction name in a binary compiled this function is "_D3addFiiZi"`. So whatever he compiles as must be what mangleof reports, as it's the same entity generating the mangle. I don't know what his source code is.

There's a way:

int add(int i, int j);
static assert(is(typeof(add) == typeof(*(int function(int, int)).init)));

Unfortunately there's no dedicated syntax for it, unlike C++. Weirdly enough, if you pragma(msg) a function type it prints it out in C++ syntax (e.g. `int(int, int)`), but if you type it yourself it won't compile.

Then there's this oddity:

Did you consider `core.demangle.mangleFunc` instead?
