Hi, I try to understand Size(), HasSize() and CanComputeSize(). It seems very strange to me that
gap> l := [];; gap> HasSize(l); false gap> CanComputeSize(l); false isn't there a missing method/attribute here? I would expect that all dense lists have these attributes set. However InstallTrueMethod(CanComputeSize,IsDenseList); doesn't change the results of the code above. My interest is that I want to display an object either by its size (if it exists or is easy to compute) or as an object by itself (in other cases).
