Abdulaziz Ghuloum e7386cd7d7 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.

Abdulaziz Ghuloum 1389f239fe Added process-nonblocking which is like process but returns
nonblocking ports.

Abdulaziz Ghuloum f69e82e6c5 Added with-output-to-port:
> (let-values ([(p e) (open-string-output-port)])
    (with-output-to-port p (lambda () (printf "Hello\n")))
    (e))

Abdulaziz Ghuloum 89def78c3c 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.
2008-04-28 14:01:49 -04:00
Abdulaziz Ghuloum 3ce6d037e4 Fixed a bug in module imports where some marks were missing in action.
(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))

  2. &message: "invalid eof after quote read macro"
  3. &lexical-position:
      file-name: *stdin*
      character: 7

Now:
> '#!eof
#!eof
