-- Predicate search. Returns the index of any value satisfying the predicate,
-- nil if no such values exists in the table. The last parameter iter is
-- optional and specifies the iterator to use (pairs is the default). The
-- predicate takes as arguments the value and the key (the order is reversed
-- because often the key isn't needed)

-- Linear search. Returns the index of the passed value if found, else nil.
