I'm trying to find some pattern in a certain series (a logistic map).
The series is infinite.
I want to get - say- 10 values from the Enumerator, examine it, and
either return something ("found") and/or continue searching. (I know
this
won't find overlaps, it's just an experiment).

Both #each_slice and #each_cons try to build an Array from the
enumerator, which is - in this case - impossible, because the Enumerator
is infinite and would eat up all the memory.

I read about lazy_select and chained filters for enum which might be a
solution but I have yet to understand them. For the time being I'm
sticking to that #map solution.

Thanks
