a view which iterates over a given < a class = "link" href = "../sequence.html" title = "Sequence" > Sequence</ a >

has infinite length, it can only be used when some external condition determines
the end. Thus, initializing a fixed length sequence with a < code class = "computeroutput" >< span class = "identifier" > repetitive_view</ span ></ code > is okay, but printing a
