Why are methods in ruby documentation preceded by a pound sign?EDIT: Duplicate of Why are methods in ruby documentation preceded by a pound sign?
Hi,
I'm trying to learn Ruby for fun at my spare time with the free Programming Ruby book. It is mostly fairly straight forward but I kept seeing notations like this KaraokeSong#to_s, which is not really explained in the earlier chapters of the book.
I know it meant <class>#<method> but it is something you can use in the code? or just a notation ruby programmers use to specifiy a method like <class>::<method> notation used by C++ programmers?

# = instance method
:: = class method
Per ruby docs:
Use :: for describing class methods, # for describing instance methods, and use . for example code.
