Background: Using core we have tables defined in a few separate files. Goal: To have column defaults be selectables which reference other tables while avoiding circular imports. To avoid circular imports I cannot always build the selects at import time, they have to be generated inside a function that takes table/col names similar to how FKs work.
It seems that a callable for Column.default cannot return an uncompiled statement. Two solutions I see: 1) Use the context provided to default callables to compile the dynamic select statement. 2) Implement something similar to FKs, using all the parent attach events to set .arg to a selectable on a subclass of ColumnDefault.
