[Cuis-dev] question about Compiler evaluate:

[Weslleymberg Lisboa]

Hi, Mark

I found 'is Undeclared' in UndeclaredVariableWarning>>defaultAction 
which seems to match what you see in the transcript.

I was able to get rid of the transcript error message by doing:

expression := '1 + x'.
[ Compiler evaluate: expression ] on: UndeclaredVariableWarning do: [:ex 
| ex resume: false] on: Error do: [:ex | ex inspect ]

To give a little context, I searched for references to the class 
UndeclaredVariableWarning. One of the results was Encoder>>#undeclared: 
where the comments mention how to disable the warning.
