string = 'foo'

string.object_id == string.each_codepoint{|x|}.object_id
# => true
string.object_id == string.each_byte{|x|}.object_id
# => true
string.object_id == string.each_line{|x|}.object_id
# => true
string.object_id == string.each_char{|x|}.object_id
# => false

I was hoping for a little bit of consistency as well.
