StepTalk , by default, does not expose all available classes. There is a reason
for that. If you would like to make a class public, you just include it in your
bundle's or framework's ScriptingInfo.plist. See similar files in StepTalk
sources. That is the designated way of doing it.

GNUstep base is special case, similar to all  GNUstep libraries. As you may have
noticed, GNUstep core is set of normal libraries, not frameworks(*). Therefore
there is no ScriptingInfo. As a work-around, there are "modules" in StepTalk
for Foundation and AppKit. What you need it to add all new public gnustep-base
classes into the Modules/Foundation/ScriptingInfo.plist.

Or ... you can use hacky-way :-) as follows:

 Environment loadModule:'ObjectiveC'.
 NSExpression := Runtime classWithName:'NSExpression'.

Btw. just for couriosity, are you using stexec or StepTalk interactive shell?

(*) - is there any reason why GNUstep-base is still a library, not a framework?
