find last

find a value in a list searching from the end

(list xs, function p) -> any

Tests each x in xs in reverse order by passing them to predicate function p.

If p accepts a single argument, p(x) is evaluated. If p accepts two arguments, p(x, i) is evaluated, where i is the index of x in xs

Returns the first x for which p returns a value that casts to boolean true.

Returns nil if xs is nil or p is nil.

Returns nil if p does not return true for any x of xs.
