byclj/s
(by f)(by f & fns)Takes a number of functions. Returns an ident function that calls the first function on a map, then the second, and so on until one of the functions returns a non-nil value, which should be an ident.
Returns nil if all functions return nil.

by-keysclj/s
(by-keys key)(by-keys key & keys)Takes a number of keys. Returns an ident function that looks for the first key in a map, then the second, and so on until it finds a matching key, then returns an ident using that key and the value found.
Returns nil if no keys are found.

identify-by-keyclj/s
