We do not have a standard signature for functions that represent this iteration. Adding support for functions in range would both define a standard signature and provide a real benefit that would encourage its use. > There are also functions we were reluctant to provide in slices form that probably deserve to be added in iterator form. For example, there should be a strings.Lines(text) that iterates over the lines in a text.
