From the docs:

   Splits _str_ using the supplied parameter as the record separator
   (+$/+ by default), passing each substring in turn to the supplied
   block. If a zero-length record separator is supplied, the string is
   split on +\n+ characters, except that multiple successive newlines
   are appended together.

String#each is actually the same as String#each_line (one is aliased to
the other).


To the OP: why do you want to exclude String? Shouldn't you allow your
user to consider a string as a collection of lines? That way, someone
using your library to work on data from a newline-separated file doesn't
have to parse it themselves, just load it into a String and call your
method on it.
