I can do this with core.logic (yes, I know that match-list isn't doing
anything much here)
(defn match-list [member list]
(membero member list))
(run* [q]
(match-list 10 [1 10 100])
(== q "worked"))
For q to come back with any values then 10 has to be part of the list [1
10 100].
I want to do the same thing where the second argument is a list of
lists. So something like:
(defn match-lists [member lists]
(map
(fn [l] (membero member l))
lists))
(run* [q]
(match-lists 10
[[1 10 100]
[1 10 100]])
(== q "worked"))
which should also return "worked". The point is that I don't know how
many "membero" forms I need at compile time, only at runtime. My initial
attempt above fails.

Is there a way to do this with functions -- or do I need to macro it?
