+# Multiple Dispatch
+
+# In Julia, all named functions are generic functions
+# This means that they are built up from many small methods
+# For example, let's make a function meow:
+function meow(cat::Lion)
+ cat.roar # access properties using dot notation
+end
+
+function meow(cat::Panther)
+ "grrr"
+end
+
+function meow(cat::Tiger)
+ "rawwwr"
+end
+
+meow(tigger) #=> "rawwr"
+meow(Lion("brown","ROAAR")) #=> "ROAAR"
+meow(Panther()) #=> "grrr"
+
+function pet_cat(cat::Cat)
+ println("The cat says $(meow(cat))")
+end
+
+pet_cat(tigger) #=> ERROR: no method pet_cat(Tiger,)
+pet_cat(Lion(Panther(),"42")) #=> prints "The cat says 42"
