Fix the ScriptCompiler's evaluate:in:to:notifying:ifFail:logged: method for non-cil contexts (e.g. the ContextVariablesInspector bottom right pane in the debugger). The old code used aContext methodClass which would exclude the variables of a receiver whose class inherited the method, rather than implemented it directly (e.g. debug (1@2) printString and in the context inspector on the Point(Object)>>printString activation try and evaluate x@y. Using methodClass excludes Point's inst vars.
At the same time eliminate its reliance on DoIt: and DoItIn:
=============== Diff against EToys-eem.304 ===============
Item was changed: ----- Method: ScriptCompiler>>evaluate:in:to:notifying:ifFail:logged: (in category 'as yet unclassified') ----- evaluate: textOrStream in: aContext to: receiver notifying: aRequestor ifFail: failBlock logged: logFlag "Compiles the sourceStream into a parse tree, then generates code into a method. This method is then installed in the receiver's class so that it can be invoked. In other words, if receiver is not nil, then the text can refer to instance variables of that receiver (the Inspector uses this). If aContext is not nil, the text can refer to temporaries in that context (the Debugger uses this). If aRequestor is not nil, then it will receive a + notify:at: message before the attempt to evaluate is aborted." - notify:at: message before the attempt to evaluate is aborted. Finally, the - compiled method is invoked from here as DoIt or (in the case of - evaluation in aContext) DoItIn:. The method is subsequently removed - from the class, but this will not get done if the invocation causes an - error which is terminated. Such garbage can be removed by executing: - Smalltalk allBehaviorsDo: [:cl | cl removeSelector: #DoIt; removeSelector: - #DoItIn:]."
