Re: [Pharo-dev] call for cleaning ideas around Spec

Since the array is recursively performing its nested elements the expression row newColumn: [ :col | col add: #topToolbar height: self toolbarHeight ] was probably to get #columSpec addHeight: #(itemSpec topToolBar #toolbarheight) which would lead to aColumn perform: addHeight withArguments: (anItemSpec perform: topToolBar with: (model/presenter toolbarheight) The trick is to see who should be the receiver In visualWorks a windowSpec contains only literals like in Spec and I do not know how they can make such difference.
