Agreed. I was trying to demonstrate that a variable, say the unassuming x, could actually turn out to be a Symbol (even though it is not prefixed with a colon). However, that is not surprising because: 1. In Ruby one can write x = :my_symbol but can't write :my_symbol = x # This is sort of equivalent to trying to write 5 = x That is, apart from specifying a Symbol literally (e.g. :my_symbol) one can only specify a Symbol by specifying the variable that references it. Like ALL objects in Ruby, to specify the object you either specify it literally or specify the variable that references it. 2. Since Ruby is a dynamically typed language a variable, say the unassuming x again, can reference different classes of objects throughout a program. As such, a variable could reference any class of object at a particular moment in time, including a Symbol object.
