Common Lisp HyperSpec (TM) http://www.cs.cmu.edu/Groups/AI/html/hyperspec/HyperSpec/FrontMatter/index.html does not index any with-<type> symbols. How is this attributable to CommonLisp? Also, would with-fixnum declare uniform arrays and vectors?
with-<type> were a toy examples. Sorry for the confusion. If I remember, correctly, real Common Lisp would look like:
(lambda (x y)
(declare (type double-float x y))
(/ x y)))
I'm not wedded to any particular syntax, though.
Yes, Common Lisp type specifiers can specify the element types of an
vector. See the first example in section 4.2.3 of the HyperSpec:
