[Sqlalchemy-tickets] Issue #4012: AttributeError in WithinGroup (zzzeek/sqlalchemy)

New issue 4012: AttributeError in WithinGroup
https://bitbucket.org/zzzeek/sqlalchemy/issues/4012/attributeerror-in-withingroup

Scott Milliken:

Commit 7c4512c did a refactor, renaming the `WithinGroup` constructor argument from `func` to `element`. It looks like a reference to `func` in `WithinGroup.get_children` didn't get updated.

Noticed because it's causing an `AttributeError` when trying to use `func.percentile_cont`.
