DSL Tools
Helpers for creating and traversing recursively nested data structures in Python. Useful for creating simple languages and abstract value domains like type and shape systems.
Contains:
- Node: Base class for building algebraic data types by having each child class declare "_members = ['x', 'y', 'z']"
- ScopedDict: Stack of dictionaries for keeping variable->value mappings while traversing nested scopes
- ScopedSet: Stack of sets for keeping sets of variables while traversing nested scopes
- NestedBlocks: Stack of lists for traversing nested scopes of statement sequences
- dispatch: calls local functions based on the class name of its argument
