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

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?
