Hi brianp
The << operator has many different uses: A googling gave
In an Array it is used to append (push) an object into a given array
In a Fixnum and a Bignum object it shifts the number bits to the
left
In an IO object it will write the object (as a string) to the IO
object.
In a String it will append the object (to_s) to the String (if the
object is a Fixnum between 0 and 255 it will convert it to the
character representation before appending it)
That means based on context it has different meanings
