+;; OK, now we need a hierarchy.    Problems:
+ ; some of the primitives as-implemented don't play well with state abstraction.
+ ; want all derived knowledge to be represented explicitly ?
+
+; Basic ideas:
+ ; In perfect world, store "possible next" set for each var.
+  ; When we activate a var, we must either assign to a parent that wants current val (how do we know?),
+  ; or choose an action that can lead to a possible next val.
+ ; Also need info going down, maybe?
+  ; Maybe we can ignore it for now ...
+  ; Can make it last priority to activate var downward, only if we're otherwise stuck.
+  ; Still, early deadlock detection is probably important.
+
+; Now an abstract subproblem should be, either:
+ ; (1) achieve a particular precondition of some active action, or
+ ; (2) achieve some precondition of some active action.
+ ; (3) achieve some active action
+; advantage of former is simplicity.
+; advantage of latter is faster termination.
+ ; and potentially, more state abstraction?
+
+; Think about (1) first.  We're in some state, have some active actions and parent commitments, want
+; to achieve a particular precondition.
+;  What matters: var and all ancestors, plus all auxillary vars on these.
+;  Plus: descenents of ancestors, subject ot some constriants.
+;  e.g., same as before.  Not clear what commitments have given us
+
+; Take a different tack: what we *really* want is maximal state abstraction for each task.
+; task termination conditions are, basically, whenever we're about to leave that envelope.

Remove the condp usage in generate

Remove the condp usage in generate

When invoking generate with a lazy-seq, the condp will hold onto the
head of the lazy-seq. For large lazy-seqs, this could cause memory
related issues.

Fixes #112
