Hi Stephan,

I have been playing with the Collection framework lately and having trouble when trying to set up executable sets of sets. The theory below illustrates the problem: the function maxima is meant to compute the maximal sets contained in a set of sets. Using the value command, I can evaluate the function for the empty and for singleton sets, but evaluation fails for any argument containing two or more element sets.

Maybe Florian can comment... Alex
