Description: Hi, I guess this is a bug:

(define (ev x) (if (syntax? x) (syntax-object->datum x) x))
(current-eval ev)
monkey --> error ..\..\..\Program Files\PLT\collects\slideshow\tool.ss:894:7: dynamic-require: unknown module: |,c:\program files\plt\collects\texpict\mrpict

The problem does not occur in:
(define (ev x) (if (syntax? x) (syntax-object->datum x) x))
1 ; <--avoids problem
(current-eval ev)
monkey --> monkey

The problem can also be avoided by requiring the library explicitly.
The problem also occurs with:
(define ev ...)
(parameterize ((current-eval ev)) (read-eval-print-loop)) --> same error after entering the first expression
Here the problem can be avoided in the same ways as above.

State changed from "open" to "closed" by mflatt at Wed, 02 Aug 2006 09:02:15 -0400
Reason>>> This was a bug in the Slideshow tool for DrScheme.
It's now fixed in SVN.

Thanks,
Matthew
