When I first started to write byLine, I made it a range. Then I
thought, "what if you wanted to iterate by 2 lines at a time,
or iterate by one line at a time, but see the last 2 for
context?", well, then that would be another type, and I'd have
to abstract out the functionality of line searching.
You mean window has current element and context - lookahead and
lookbehind? I stumbled across this article
http://blog.jooq.org/2016/01/06/2016-will-be-the-year-remembered-as-when-java-finally-had-window-functions/ it suggests that such window abstraction is generally useful for data analysis.
