Without:
    b = A( b ).transform( c );
    Or rather: don't store b as int in the first place.

    Accessing the stored integer value:

    A bleh = ...

    int foo = bleh; // use operator int () const { return value; }


I agree with Waldo. Such hacks aren't worth it IMHO, and the
original syntactical problem can be solved easily.
