I tried to debug another parsing issue with the Squeak importer (

   ^self perform: #<! !

is parsed as '^self perfom: #<!'. I have used the Debugger package
to step through things. The stepping in the debugger mostly works
until a >>#printString on the context inspector creates a DNU and
then things are stuck.

We do have the same problem in VisualGST when printing an Object
to a String. I think for the time being (e.g. not having mirror
based reflection) is to create a selector in the DebugTools so we
can burry a pokemon exception in there that will either return a
String or an error message.
