Hi is their anyway for boost to allow only explicit conversion...

like class MyInt
{
// some code inside....
    operator int() {}
};

myIntCalc(int, int);

MyInt a, b;
f = myInt(a, b); // compile error no implicit conversion.

int x = boost::numeric_cast<int>(a); // k allow
int y = static_cast<int>(b); // k allow.
