Module edit_form 

EditForm: a Form built together with what setting each of its fields does — for an operation with many fields, whose events are then answered by the setter of the field they set (see EditForm::set) rather than by matching their keys. Every setter gets the whole Edit: a field may set the step’s arguments or its session.

An operation only ever hands out the form (EditForm::into_form); the setters stay its own, built again for each event. A setter may capture what the form was built from — the part as the step sees it — for what setting a field implies for others: another sketch picked brings its own axis, a selection picks the construction it fits.
