I don't have to "look close enough"

This was the original context (specification):

names = ["Jane", "Michele", "Isabella"]
# current behaviour
names.each do |name|
  print name
end
#Question: How can I alter the behaviour of "each" in the following
way:
names.each do
  print item         # "item" is used by default
end

The specification is very simple.

Your solution does not work in this context.

The solution from Gray works 100%.

If you like, you can still modify your solution to pass the
specification.

If not, feel free to setup a new context (specification), but please
use a new topic.
