compile() (orast.parse(), which calls it) can return the ast for some source code, converted to a Python object version of the AST. But this AST is not optimized (with_PyAST_Optimize).

Static Python re-implemented_PyAST_Optimize for this reason. If we expose a way for them to get an optimized AST, they won't have to.

For performance, it would be better not to call another API function on a Python AST, but to add an API option that runs_PyAST_Optimize before converting the AST to Python.
