Hi Sven, I am looking at NeoCSV, and I would like to add it to Moose by default. During the review, I noticed that it relies on perform: addRawField: accessor "Add a field based on an accessor to be written as a #raw field" self addFieldAccessor: [ :object | self writeRawField: (object perform: accessor) ] I would prefer to have it modified to simply use value:. In this way we can pass blocks as transformation specifications. Why is this important? Because we often have values that we want to export but that do not have a direct correspondent in a unary method. Would it be Ok to make this modification?
