> If you create a function that is defined in ddl, it currently requires that a translator be extended to add a pushdown function and handling.  It would be better if there were a way to do this entirely in ddl.  This could be either/or:
> 1. when the function is defined by an expression rather than a more complex procedure statement, we should check to see if that can be inlined.
> 2. provide a way to match source functions.
