Accepting hint to remove Templates.setDefinesMainProject(wiz, false); from source code.
Comment 3 Jan Lahoda 2012-04-19 07:33:48 UTC 
The given usecase should work now (will basically remove the enclosing expression statement from its parent). Also added a warning when an expression is to be removed from the parent and it is non-void, as that may lead to unintended effects:
