Consider two methods:

void interest (double arg1, bool minor);

void interest (double arg1, int factor);

The call: interest(5.5, 5); is ambiguous because 5 will freely convert to a bool. 

I was wondering what y’all would think of narrowing this behavior by this addition:

void interest (double arg1, explicit bool minor);

Potentially, this could be applied to all arguments:

void explicit interest (double arg1, bool minor);

Thanks,
