I guess this is not named "cycle" to avoid conflict with "Data.List.cycle".
I was also wondering why it is "cycle1" instead of, say "scycle". It can be
thought of as cycling just one value instead of cycling a list in case of
"Data.List.cycle". I Just made up this explanation, original writers would
know better. I would prefer "scycle" which is consistent with other
functions in this package like "stimes", cycle1 sounds a bit random at
first look.
