Stack top is really usefull because it contains the result of last expression evaluation.
Since we took the habit of composing message sends without decomposing into temporary variables, it avoid selecting sub-expression and re-evaluating subparts, or entering into each message to gain finer understanding...

For thisContext, I don't really see the interest, but maybe someone will find a use case��

thisContext is useful if you want to inspect the sender chain yourself e.g. when developing tools like the debugger *with* the debugger.

I use both thisContext and stackTop regularly. thisContext maybe once a wee, stackTop probably multiple times a day.

So explain to me how?
