Re: [Algorithms] General purpose task parallel threading approach

[Conor S. <bor...@ya...>]

There is an important distinction between "seeing" information and "changing" information as well. It may not always be a good idea to hide it, but it's often a great idea to control it (and how it's presented). 

And controlling how it is presented is a great reason for encapsulation and polymorphism.

Cheers,
Conor

No, but I am arguing that hiding information from everyone isn’t
necessarily a good idea either.

Hold on, are you actually arguing against polymorphism and
encapsulation in general?

And the corollary to that is most generic/flexible systems are
implemented such that you cannot get useful information out of them without
executing them.

If the genericity or flexibility comes at the price of hiding
information, then it’s not as desirable. A useful attribute to consider is
whether you have to run code in order to make reasonable assumptions of its
behavior. If you do, it is less desirable than if you don’t.

I think the whole point of the
other side of this discussion is that generality and flexibility are not
necessarily desirable features.
 
In what sense is less flexibility preferable? I mean, I get
that in a certain specific scenario you may go for a solution that is less
flexible if it offers, say, more performance, but that doesn't mean that
everything else being equal you wouldn't prefer to have the flexibility too.
