Title: About Symbols | Koans 

* Symbols as strings are not RubyContants
i.e :"yo yo" does not include?(RubyConstant)

* Symbols can be built using interpolation

* A Ruby constant is like a variable, except that
its value is supposed to remain constant for the
duration of the program.

* In object-oriented and functional programming,
an immutable object is an object whose state
cannot be modified after it is created.
