 The RPython Typer is the bridge between the Annotator_ and the low-level code
-generators.  The annotator computes types (or "annotations") that are
-high-level, in the sense that they describe RPython types like lists or
-instances of user-defined classes.  In general, though, to emit code we need
-to represent these high-level annotations into the low-level model of the

 In theory, this step is optional; some code generators might be able to read
 directly the high-level types.  However, we expect that case to be the
