Major changes to the interactive repl:
...
- We can now redefine imported identifiers.
- We can now use let-syntax, letrec-syntax, and modules at
top-level.
Hand-wavey Repl Semantics:
- Imported identifiers mean what they meant previously. In
particular, you cannot set! imported identifiers.
- An imported identifier may be redefined using define. Once
something is defined at the top-level, a specific location for it
is created, and all definitions, references, and set!s to that
variable go through the top-level location.
- Re-importing an identifier shadows the top-level location.
- Redefining re-exposes the top-level location.
- and do on.
- A reference to an unbound variable also fabricates a top-level
location for that variable.
Let's see how this goes.

Fixed the definition of identifier? and id? in expander so that only

top-make-wrapped (possibly annotated) symbols are identifiers. It
used to be that symbols were considered identifiers by the previous
definition.

(Note from Kent, extracted from chez scheme release notes, follows)
This always worked:
(let ()
(define-syntax from
(syntax-rules ()
[(_ m v) (let () (import m) v)]))
(module a (x) (define x 'x-of-a))
(from a x))
Didn't work before this change:
(let ()
(define-syntax x-from-a
(syntax-rules ()
[(_) (let () (import a) x)]))
(module a (x) (define x 'x-of-a))
(x-from-a))

Unhandled exception:
Condition components:
1. &who: let
2. &message: "not an identifier"
3. &syntax:

6. &trace: #<syntax (wrong a 12 (printf "a=~s\n" a)) [byte 216 of test.ss]>
For a file containing:
(define-syntax right
(syntax-rules ()
[(_ a b c) (let ([a b]) c)]))
