[squeak-dev] Side effect of script _ -> :=

Just a note that whatever script is used to transform _ into := in the
trunk. It does not recognize comments as in

 analyseTempsWithin: scopeBlock "<BlockNode>"  rootNode: rootNode "<MethodNode>"
-       "N.B.  since assigment happens _after_ the value is evaluated
the value is sent the message _first_."
+       "N.B.  since assigment happens :=after:= the value is
evaluated the value is sent the message :=first:=."
       value analyseTempsWithin: scopeBlock rootNode: rootNode.
       variable beingAssignedToAnalyseTempsWithin: scopeBlock rootNode: rootNode

As for the example above, the author should not have used underscores  
but should actually have made the words bold or italic.

The refactoring browser can trivially do this, it does pretty print
the code afterwards though:

ParseTreeRewriter new
        replace: '`var _ ``@object' with: '`var := ``@object' when: [ :node |
                node position notNil
                        and: [ node methodNode sourceText notNil
                        and: [ (node methodNode sourceText at: node position ifAbsent: [ ])
= $_ ] ] ];
        yourself
