That depends on how you interpret the plural ("immediate superclass and
direct interfaces") in its docstring.

((seq? [[1] false] [(1) true] [[java.util.Collection] false])
(sequential? [[1] true] [(1) true] [[java.util.Collection] false])
(seqable? [[1] true] [(1) true] [[java.util.Collection] true]))
I personally favor seqable? as the test for plural return values.
sequential? almost qualifies, but excludes sets. seq? fails on account of
rejecting even vectors, but you may feel differently.
