Metacello - versionMap subclassing

[Dale Henrichs]

Since versionMaps are classes, I suppose the question can be asked, "Why not use subclassing for extending versionMaps or dealing with platform dependencies?"

I don't think that it is a good idea to rely on subclassing as the primary way to do things in Metacello. I don't want to get backed into a corner where multiple inheritance is required.

I would rather leave subclassing as a last resort than depend upon it for central features.

With that said, for individuals who are trying to solve specific configuration issues, subclassing may turn out to be the most pragmatic solution.
