[Cuis-dev] question about Compiler evaluate:

[Mark Volkmann]

I see the message I'm trying to capture is written to the Transcript in the
UndeclaredVariableWarning instance method defaultAction.
So it doesn't exist as the value of any instance variable I can access.
I don't see an easy way to get such error messages from Compiler evaluate:.
