Hi,
A thought occurred to me about optional<>
This is again about having the constructor non-explicit
(I would really like to have this :-)
could you use partial specialization to do this ?
The code below has the desired behaviour.
usage gives the programmer the ability to choose whether the constructor
is explicit or not
Are there any problems with this approach ?
Vin
template< typename T, bool bIsExplicit = true >
class C
{
public:
C( const T )
{
g = 9;
};
};
template< typename T >
class C< T, true >
{
public:
explicit C( const T )
{
g = 2;
}
};
void test1(C<int> c)
{
int grr = 90;
}
void test2(C<int, false> c)
{
int grr = 99;
}
