Local Variables versus Methods


# If a local variable exists with the same name as a method, 
# the local variable will be referenced 
# unless you put parentheses behind the method or use self.methodName.

def colors(arg1="blue", arg2="red")
    "#{arg1}, #{arg2}"
end

colors = 6
print colors

# The above outputs 6.
