Reviewing the AST to make sure it accurately describes Python.  Once I
get started on the transformer, there will be lots of code to write.
I don't know how easy it will be to split that task up.

Unfortunately, no.  The ASDL stuff describes the AST -- a compiler
intermediate representation.  The error recovery needs to be added to
the parser.
