+# Structs
+
+In Tomo, you can define your own structs, which hold members with arbitrary
+types that can be accessed by fields:
+
+```tomo
+struct Foo(name:Text, age:Int)
+...
+>> my_foo := Foo("Bob", age=10)
+= Foo(name="Bob", age=10)
+>> my_foo.name
+= "Bob"
+```
+
+Structs are value types and comparisons on them operate on the member values
+one after the other.
+
+## Namespaces
+
+Structs can define their own methods that can be called with a `:` or different
+values that are stored on the type itself.
+
+```tomo
+struct Foo(name:Text, age:Int):
+ oldest := Foo("Methuselah", 969)
+
+ func greet(f:Foo):
+ say("Hi my name is $f.name and I am $f.age years old!")
+
+ func get_older(f:&Foo):
+ f.age += 1
+...
+my_foo := Foo("Alice", 28)
+my_foo:greet()
+my_foo:get_older()
+```
+
+Method calls work when the first argument is the struct type or a pointer to
+the struct type.
