+### NAN_CONSTRUCTOR(methodname)
+Use `NAN_CONSTRUCTOR` to define constructors used by your V8 accessible methods:
+
+```c++
+struct Foo {
+  NAN_CONSTRUCTOR(Foo);
+  ...
+};
+
+NAN_CONSTRUCTOR(Foo::Foo) {
+ ...
+}
+```
+
+The reason for this macro is that constructors have no explicit return type and cannot thus be declared the way methods are.
