- All of the specific kinds of canned parsers for Python 3.7
- These are derived from "compile-modes" but we have others that
- can be used to parse common part of a larger grammar.
- For example:
- * a basic-block expression (no branching)
- * an unadorned expression (no POP_TOP needed afterwards)
- * A non-compound statement
