# This is a contrived example. 
# But, this simple example demonstrates some code I have seen where not understanding the difference 
# between 'and' and '&&' has caused unexpected behavior.

# The intent is to evaluate the 3rd clause if the 1st and 2nd clause is true.
# Again, this is a contrived example.
# But, imagine that the 1st and 2nd clause is a method invocation or something like that.
# This is a classic example where the goal of terseness really caused problems.
