Hi,

One result of Friday��s Pharo Sprint in Chile: Use the nice icons of the new text editor
to display some of the semantic errors nicely (instead of breaking flow with a intrusive dialog):

This was done by Johan based on the prototype Miguel did in September:

1) unused temps:

(the ��drag the crosshair��r is an artefact of the snapshot tool)

2) temps used that are not initialised:

In a next step, we need to integrate that with the QA tool�� no need to have this reported
twice.

What is nice is that this simplified the Compiler: instead of having an Exception and raising
it, we now just annotate the AST:

unusedVariable: variableNode

variableNode propertyAt: #semanticWarning put: 'unused variable��

(this is very simple for now, with a node just being able to have one kind of semanticWarning).

SemanticWarningIconStyler is what adds the icon. It has 4 methods with one line each.
