python3-pymbolic 2022.2-2 (amd64 binary) in ubuntu noble

 Pymbolic is a small expression tree and symbolic manipulation library. Two
 things set it apart from other libraries of its kind:
 .
 * Users can easily write their own symbolic operations, simply by deriving
  from the builtin visitor classes.
 * Users can easily add their own symbolic entities to do calculations
  with.
