Gets a Python dict of the unbound references in comp.


Defined in python/core/impl/transformations.py.

Compuations that are equal will have the same collections of unbounded references, so it is safe to use comp as the key for this dict even though a given compuation may appear in many positions in the AST.


  • comp: The computation building block to parse.


A Python dict of elements where keys are the compuations in comp and values are a Python set of the names of the unbound references in the subtree of that compuation.
