The way that the compiler munges types with arguments together

In some cases the compiler believes type declarations on array
elements without checking them, e.g.
And as long as we're wishing, it would be awfully nice if INSPECT could
also report on closures, telling about the values of the bound variables.

The compiler assumes that any time a function of declared FTYPE
doesn't signal an error, its arguments were of the declared type.
make sense to add another flag (CHECKED?) to DEFKNOWN to
identify functions which *do* check their argument types.)

- Thanks for the bug report, nice to have this one fixed. It was a bug

- Probably the same bug exists in SBCL.

-40:
- TYPEP treats the result of UPGRADED-ARRAY-ELEMENT-TYPE as gospel,
- so that (TYPEP (MAKE-ARRAY 3) '(VECTOR SOMETHING-NOT-DEFINED-YET))
- returns (VALUES T T). Probably it should be an error instead,
- complaining that the type SOMETHING-NOT-DEFINED-YET is not defined.
-
41:
TYPEP of VALUES types is sometimes implemented very inefficiently, e.g. in
(DEFTYPE INDEXOID () '(INTEGER 0 1000))
:ELEMENT-TYPE, but in sbcl-0.6.9 this is not defined for
WITH-OUTPUT-TO-STRING.
