Yes :-))
I've uploaded the new version which compiles and runs properly with VC6.0
NOTE: I've found when running the test that VC6.0 creates a temporary copy
in the following situation:
void foo()
{
MyStruct v = 2;
optional<MyStruct> opt(v);
(*opt == v ) ; // A temporary copy of the value inside 'opt' is created
here!
}
The weird thing is that (*opt) is a proxy with a 'operator T const&() const'
and this operator *is* called -as can be seen with the debugger- but only to
create the temporary that is passed to operator ==
Anyway, with a small twist of the test it now passes with VC6.0
