####### PROXY PATTERN #############

### way #1
## The following code implements the proxy pattern in the traditional
## manner, i.e. the proxy mirrors the methods of the real object (e.g
## drive) and delegates accordingly

class RealCar
	def drive
		puts "vroom,vroom..."

####### COMMAND PATTERN #############

### 1st attempt
## The following code implements the command pattern in the traditional
## manner, i.e. with a separate class for each command. We aim to
## implement a do / undo application that increments a global aggregate
## (or decrements it for the Undo)

class	Command
	def do_command

####### STRATEGY PATTERN #############

### way #1
## The following code implements the strategy pattern in the traditional
## manner, i.e. with a separate class for each strategy (xxxPayment),
## which is then passed in the constructor of the Context class (in
## this case the Purchase class).  The Context then selects a strategy
## at construction time and delegates its stragegy method (i.e. pay) to
## the strategy object
