Yeah, that wording is somewhat poor. It really should say something like "Roles can provide attributes." Except, of course, the Role actually has the attribute if you consider the class as a composition of separate roles with the class itself being an anonymous role that is instantiable (which, if you think about it, is one of the two major differences between a class and a role (the other being that a class has to be complete and a role can be incomplete)). And, in any case, the instance of the class is the thing that actually has the attribute, the class merely being the template by which instances are created.

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

[Corion]: ambrus: "the other" ;) To me, "normal" for GUIs means (0,0) is left-upper corner of the monitor/window. But for Prima, the lower-left corner it is ;)
[Corion]: Which would be OK for mathematics and paper, for me ;)
[ambrus]: Ok, so Prima has a postscript-like coordinate system
[Corion]: ambrus: Yes, which kinda makes sense because Prima also has Postscript output or something, I think
