No.
Perhaps I should clarify my terminology a bit.
A binary relation R is an association between elements of two sets S1 
and S2. In fact, R is a set of some tuples (s1, s2) where s1 is taken 
from S1 and s2 is taken from S2. Now, if we consider rather special case 
of S1 == S2 == ST, where ST is a "set of tuples" and consists of the 
very tuples that constitute the relation R we will get the main 
reflexive structure behind Pile.

As far as I remember, this is similar to Brian's arrows that have other 
arbitrary arrows as their endpoints (i.e. an arrow points from one arrow 
to another arrow).
