[pure-lang-users] Bug with list comprehensions

As if this weren't weird enough, if you type this in right after 

 > let y = [1%2, 3%4];
 > [(i,j); i=y; j=y]
 [(0+:1,1L%2L),(0+:1,3L%4L),(0+:1,1L%2L),(0+:1,3L%4L)]

Note that 
 > let x = [1%2, 3%4];
 > [(j,k); j=x; k=x];
 [(1L%2L,1L%2L),(1L%2L,3L%4L),(3L%4L,1L%2L),(3L%4L,3L%4L)]

Works. So my guess is that the constant i defined in math.pure is
getting mixed up with the i in [(i,j); i=x; j=x];

e.r.
