Subject Re: [lang][collections][functor] Functors move
Date Mon, 09 Jun 2003 14:28:36 GMT
The functors have been one of the most discussed and fought about pieces of code in commons.

View A is that they should reside in [lang] and [collections] should depend on [lang].

View B is that each commons component should be independent if possible, and that these are
primarily [collections] influenced functors.

I fought for option A for a long time, but a realistic position needed to prevail and option
B won out.

As far as your problem goes, the Factory classes are exactly the same in [collections] as
were in [lang].

One problem with having them in [lang] was that these classes were not a full functor implementation.
That can be found in [functor]. There may be a case for additional factory-like behaviour
in [lang] at some point, but I don't want to duplicate the [collections] code.
