Yes and no.  Should (lambda 3) be accepted by functionp?  What about
(lambda () . 3) ?  What about (lambda () (+ . 1)) and other errors?

#[abc] is an object of "function type", which is why functionp
returns t.  I don't think that it's terribly important if when calling
it, you get an error, since that can happen for syntactically valid
functions as well.
