find-relevantclj
(find-relevant m element ks)Search the given map for the entry corresponding to [[element]], considering only the relevant keys. The relevant keys are obtained by ignoring any suffix of [[ks]] for which [[element]] has nil or missing values. We require that there is at least one relevant key to find a match.

pred returns a truthy value, or nil if no such item is found.
