I think there is a range of opinions regarding the parens, yes or no? question in the Ruby community. I am sure, however, that leaving the parens off is the surest way to confuse people who are newly arrived in Ruby from say Java. I can’t tell you the number of times that I have confused a room full of newly minted Ruby programmers because I left the parens off of some example. Put the parens back on and their faces light up.

Hey thanks for the kind words, I’m glad that you are finding the book useful. The funny thing about the factories patterns is a) that I wasn’t 100% clear on the difference between the two before I started researching the book and b) given Ruby’s dynamic nature, you really don’t find many of examples of the classic factories in real Ruby code.

Oh, and in the interest of fairness I’m going to include some Marvel characters in my next book.

About the only thing I would critique is that from what I have observed from most frameworks in Ruby is that the parens are omitted when there is only one arg. It reads betters:

# d = SimpleItem.new()
# d.extend(Decorator1)
# d.extend(Decorator2)

to

# d = SimpleItem.new
# d.extend Decorator1
# d.extend Decorator2
