 To check if a type is a certain type, use `[$is::typeName $type]` or `[expr {[$typeName $type] == typeLookingFor}]`.
+To get details of a type, use `[$details $typeName]`. It should return a doc string or similar.
 ===== Type names =====
 Type names come in two forms: canonical and inline. Canonical type names are either a name, or a list with the first parameter as its name. For example, a type name for meters could be "m", and a type name for acceleration could be "{accel m s}" (note meters and seconds as type parameters). All the type parameters specific to the type, and should not be assumed to be referencing an existing type.
 Inline type names are a mixture of wildcards and symbol/number characters. For example, the type signature of acceleration could be expressed as "*/*^2". One thing that signature would match to is "m/s^2", with "m" and "s" as the types' parameters. The canonical form would be "{accel m s}". Not all types have inline representations.
+===== Types are reactive =====
+To get the type list (or any type list, lists can coexist), use <code>
+When the types are /types/ {
+  lassign $types box unbox is typeName details
+  # example using the newly imported types
+  puts [$unbox::mm "10 mm"]
+}
+</code>
