I think it makes the class definition harder to read than
virtual void fun1(int,int) = 0;
virtual int blah(float) = 0;
However, I can see defining a whole class as 'interface' by use of
'virtual' in the class definition:
class virtual ABC {
public:
void fun1(int,int);
int blah(float);
};
which should mean that all functions are virtual and pure (including
the compiler-provided destructor and the assignment op). The d-tor
should be trivial in that case IIUIC and its purity is superficial.
Not sure it can be done or whether it already has been suggested.
