So basically I get the error "function button(lua_State* L) is
not callable using argument types ()" whenever I try to
lua_register a function.
```
lua_register(L,"button",button);
```
but whenever I use the function pointer I get the error
"lua_register is not callable using argument types (lua_State*,
char*,extern (C) int function(lua_State* L)"
```
lua_register(L,"button",&button);
```
Is this a bug, or am I doing something wrong here?
lua_register takes function pointers that in the form of
lua_CFunction, an alias you can find declared in
derelict.lua.types [1]. As you'll see there, it is declared to be
both extern(C) and nothrow. Make your button function nothrow an
you should be good to go.
