Comments

There are basically two ways of commenting in ruby:

# This is a comment

str = 'hello' # this is a string
p str     # now string
  .chars  # now array

=begin
this is not parsed as code
until we reach the..
=end

You can use strings as comments, if you don’t mind creating string instances.

"This is a number
and it's 37"
a = 37

If you want comments or notes in the middle of instructions…
NOT breaking lines…
you can use tap or this:

class Object; def nb! = self.tap {}; end

str = 'hello again!'
p str.nb! {"String is here"}.chars.nb! {"Now it's Array"}
