Remember that lines and words are lazy, so do you really need to process in
chunks?
If you do, you can build the chunks easily with X lines, you could do:
for "filename".IO.lines(:!chomp).batch(3) -> @batch {
say .join;
}
Similarly for words, of course. Note the use of :!chomp to keep the newlines.
If you don't want them, just don't specify it: removing newlines is the default.
