Well, hm, I have as yet not thought about the subject line in that report.

But now I think that Heap #species problem is more subtle: (self species  
new) cannot pass the sortBlock of Heap (nor any other clone-invariant  
instVar) for users like #collect: and friends; therefore Array is passed  
by Heap #species.

But #copyEmpty can pass sortBlock and *whatsoever* to clones ;-) With  
#copyEmpty in place of (self species new), sending #species would be  
mainly in support of #= and #copyEmpty, throughout the collection  
hierarchy.

BTW hey Traits guys, did you discover something like the above during your  
reengineering of the collection hierarchy, that would be interesting to  
know !
