Question: Strange Behavior - Bug?

eqset := {e1, e2, e3, e4, e5, e6, e7, e8, e9, e10, e11, e12, e13, e14, e15,
          e16, e17, e18, e19, e20, e21, e22, e23, e24, e25, e26, e27, e28};
for s in eqset do print(s) end do;

Error, too many levels of recursion

If I then do

S := {1,2,3,6,3,6,8,2,3,6};

for s in S do print(s) end do;


for s in eqset do print(s) end do;

has the correct output.

What am I doing wrong?
