ab4514bb56 Use symbols instead of identifiers for poorly-printing struct types. 
This case only comes up when something else unfortunate has happened
with type printing, but the current implementation can lead to paths
in the type printing.

da574a47d0 Handle in-vector with range arguments. 
* Add `normalise-inputs` to special function env.
* Treat eta-expansion specially. Now
    `(lambda (x ...) (f x ...))`
  will typecheck like `f` but with a type restricted to
  the size of `x ...`.

  Currently, this special case only works for non-polymorphic
  functions.

5d4477d08d safe & efficient (-> Any Boolean) contract 
New strategy for compiling the (-> Any Boolean) type to a contract.
When possible, uses `struct-predicate-procedure?` instead of
 wrapping in `(-> any-wrap/c boolean?)`.
Makes exceptions for untyped chaperones/impersonators over struct predicates;
 those are always wrapped with `(-> any-wrap/c boolean?)`.

This change also affects (require/typed ... [#:struct ...]), but not #:opaque
