Yeah. I also want this. I have a project where I want to use blobs, but the
darn blobs 'blob' with the wrong ones. It would be nice if you could for
instance, declare blob element 1 as, say, A, and elements two and three as B
and C. Then you could give an 'interactions' list. B for A, C for B and B
for C, you see?
(A)===(B)
//
(C)
Forgive the crude ascii art.
