+# Objects
+
+In Nimrod, objects are like structs from C family languages and define a grouping of fields.
+
+``` nimrod
+type
+  Animal* = object
+    name*, genus*, species*: string
+    age: int # None of your business!
+  PAnimal* = ref Animal
+
+proc sleep*(a: var Animal) =
+  a.age += 1
+
+# create a new Animal, not allocated on the heap
+var carl = Animal(name : "Carl",
+                  genus : "Lama",
+                  species : "glama",
+                  age : 12)
+
+# Allocate an Animal on the heap
+# Note that the pointer is immutable, not the pointee
+let mittens: ref Animal = new(Animal)
+mittens.name = "Mittens"
+mittens.genus = "Panthera"
+mittens.species = "Leo"
+mittens.age = 6
+
+# This also goes on the heap since PAnimal is a
+# reference type
+let spot = PAnimal(name: "Spot",
+                   genus: "Canis",
+                   species: "Lupus",
+                   age: 1)
+
+# Same as before, only pointer value is unchangeable
+spot.age = 2
