you are just assigning a to an array literal
This is equivalent to
a = Array.new(['one','two','three'])
Like Siep said, array access a[0] will raise the error.
r

I know it's bad behaviour :slight_smile: But I'm just fiddling with ruby.

class Array
    def (elem) # just get rid of the "="
      raise 'Yesss... It works!'
    end
end

a = ['one', 'two', 'three']
p a

Didn't work also. It just prints: ["one", "two", "three"]

try

p a[0]

is just a method. You chanced it. To verify if your change works, you
'll have to use the method. If this is not what you want, what
outcome did you expect?
