Isn't dlopen() for Linux and LoadLibrary() for Windows?  Or are 
you running Windows Subsystem for Linus (WSL) or mingw?


Just to add to the above discussions (for future searchers). I 
also found a demangle() in std.demangle that I used in the 
example below.

alias addSevenFuncSignature = int function(int, int);

addSevenFuncSignature  addSeven;
writeln(addSeven.mangleof);
writeln(demangle(addSeven.mangleof));
