That we don't  have a  way to  create accessor  (specifically the getters) that do lazy evaluation?  Lazy initialization? What do you want to do?
SomeClass>>aVariable
  aVariable isNil ifTrue: [aVariable := "sensible thing to do"].   ^aVariable
How would the refactoring engine figure out what you want to do? Normally you just change the code directly in the changes browser.
 > And last but not least, if  I attempt to edit a method in the new  > window  "Changes:  refactor  class,  accessors"  I  get  an  MNU:  > OR2AddMethodChangeNode(Object)>>doesNotUnderstand: #selectedClass.  I  cannot reproduce  the  problem in  the  standard OmniBrowser.  I  commonly edit the changes before applying the refactorings.

Looks like a bug in OCompletion. I am still using ECompletion, so I've not seen that bug before. Lukas -- Lukas Renggli http://www.lukas-renggli.ch
