seq?

tests whether the provided forms are sequences

Usage: (seq? form+) (!seq? form+) (is-seq form)

If all forms evaluate to a valid sequence, then this function will return #t (true). The first non-sequence will result in the function returning #f (false).

An Example

(seq? '(1 2 3 4) [5 6 7 8])

This example will return #t (true).

Like most predicates, this function can also be negated by prepending the ! character. This means that all the provided forms must not be valid sequences.

(!seq? "hello" 99)

This example will return #t (true).
