How would you translate this class to D:

#class _U_MENUorID

#public:






#void testfunc( _U_MENUorID x = 0U ){}

The straightforward translation would be:

#class _U_MENUorID

#public:






#void testfunc( _U_MENUorID x = null ){}

but it's not quite as usable as the C++ version.

Any ideas?

Try 2:

#struct _U_MENUorID {












#void testfunc( _U_MENUorID x = _U_MENUorID(null) ){}

It'll be efficient (no new's, pass by val) but needs an explicit cast 
(for both the default value and every passed parameter).

Take somefunc for example. C++:

#void testfunc( _U_MENUorID x = 0U ){


#void usage(){





with the 'straightforward' D conversion I need an extra check in the 
function. Also, I must create instances of the class first :(

#void testfunc( _U_MENUorID x = null ){


#void usage(){
