who said anything about writing code until it works? i may have class A, B,
and C. C requires B, and A extends C...further A, and B were designed as
stand-alone, independent objects. there must be a clean way to determine
that when A, B, and C are called as resources in a single script, they
should only be defined once. also, each must specify what resources they'll
consume independently.
because of the design, which there is nothing wrong with it (say B is a base
object of a specific db implementation, C is a db consumer, and A is a
specific implementation of C), this delima is natural. it is by design, is
not faulty, and works. i'm not getting your point?
