I suspect that just wrapping everything in a call to lazy-seq cannot
work
in this case. In the implementation of walk, the branch for handling
seqs
contains a 'doall', which I think will realize the entire sub-sequence
at that point
(while holding the head of the sub-sequence in memory too),
defeating your attempts to make it lazy by "wrapping" the recursion.
Just my suspicion...I'm still trying to get a grasp on lazy sequences
myself.
