It solves the typing problem because it's shorter, but it doesn't solve
the problem that you will in many cases have to create 2 features in
many classes instead of only one (for example: append_string and
append_line, put_string and put_line). And some people will probably
mistake the 2 features.

If eol is a once string then it's created only once in each program.
