There's no inconsistency.  "each" is a message you send to objects
that have a collection or series of elements to iterate through.  An
Array instance is such an object.  But IO is a Class object, and has
nothing that "each" would make sense for.  An IO.each class method
would thus be out of sync and inconsistent with how "each" is used
elsewhere in Ruby.
