some

(some predicate &rest sequences)

Applies predicate to one element of each sequence at a time and returns the first non-nil result, stopping as soon as one is found; if every element fails it returns nil. Each sequence may be a list or a string (whose elements are characters). Note the return value is the predicate's result, not necessarily t. With more than one sequence the predicate receives one argument per sequence and the walk stops as soon as the shortest one runs out.
