Can you flesh this out with the added complication
that my SQL?? thingy wants to include in its
expression some kind of Python function that sits at
the module level, such convert_birthday_to_age?

My fear is that even with an AST at my DSL library's
disposal, I would still want hints from Python as to
better ways to scope things in the AST given to me,
and without actually changing the Python bytecode, I
still have my hands tied.

Or am I being too pessimistic?  Or does your proposal
already account for that?
