It's the same convention as with other Semigroup-like functions, such as
`foldl1`, `scanl1`, etc.
Doesn't really makes sense to distinguish between `cycle` and `cycle1` in
this case, but that's just bike shedding.
Also, at some point in the future, `cycle` can go in `Data.OldList` and be
replaced by `cycle1`, renamed accordingly.

Riedel: What you seem to be searching for looks more like what we know as
`cycle :: [a] -> [a]`, and in fact there is its generalisation at http://hackage.haskell.org/package/base-4.10.0.0/docs/
Data-Semigroup.html#v:cycle1 Why is this function called cycle1, not cycle? What does the “1”
stand for? I guess this is not named "cycle" to avoid conflict with
"Data.List.cycle". Why? We have qualified imports. It seems very wrong to add single
characters to identifiers to denote name spaces. 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". Also Data.List.cycle cycles only one value. It is just that this single
value happens to be a list. If you specialize cycle1 to the list monoid,
you get exactly Data.List.cycle. All the best,
Wolfgang
