+# Constructors as functions
+
+An enum’s constructors can also be used like functions. For example:
+
+```rust
+# enum Message {
+# Write(String),

+let m = Message::Write("Hello, world".to_string());

+let x = foo("Hello, world".to_string());

+This is not immediately useful to us, but when we get to
+[`closures`][closures], we’ll talk about passing functions as arguments to
+other functions. For example, with [`iterators`][iterators], we can do this
