Can no longer interactively enter! module from the shell

[Greg Rosenblatt]

Given a module defined in example.rkt:

```

#lang racket/base
(provide example)

(displayln "loading example")

(define example 5)
```

I used to be able to enter example.rkt with an interactive session from the shell like this:

> racket -ie '(enter! "example.rkt")'

Welcome to Racket v7.3.
loading example
> example
; example: undefined;
;  cannot reference an identifier before its definition
;   in module: top-level
; [,bt for context]
> ,bt
; example: undefined;
;  cannot reference an identifier before its definition
;   in module: top-level
;   context...:
;    eval-one-top12
;    /Applications/Racket v7.3/share/pkgs/xrepl-lib/xrepl/xrepl.rkt:1477:0
;    /Applications/Racket v7.3/collects/racket/repl.rkt:11:26

The module still seems to be loading, but my interactive session hasn't started in the module context.  Racket 6 used to start my interactive session in the module context.

Was this change in behavior intended?  Is there a new way to achieve what I'm trying to do?

This works for me the way you describe:

```
[samth@huor:/tmp cs-snap] r -ie '(enter! "x.rkt")'
Welcome to Racket v7.8.0.7 [cs].
loading example
"x.rkt"> example
5
"x.rkt">
```

Perhaps there was a problem with 7.3 that you're running into? Can you
try with the 7.8 release?

Thanks, your output helped narrow down the issue.  It looks like the problem is actually with the regular (non-Chez) variant.

When running with Racket v7.8 [cs] I see the same (expected) behavior as you:

> racket -ie '(enter! "example.rkt")'

Welcome to Racket v7.8 [cs].
loading example
"example.rkt"> example
5
"example.rkt">

However, the regular variant of Racket v7.8 still has an issue:

> racket -ie '(enter! "example.rkt")'

Welcome to Racket v7.8.

I tried a few more versions of Racket, and this broke between 6.12 and
7.0, probably due to the new expander at that time. I'm surprised that
it works on Racket CS, though.
