It > includes validation of input types and deduction of accumulator or return > types. Argument type inference (i.e. deducing a type for {{NULL}}) will be > introduced in a later step. The interfaces replace the need for > {{PlannerExpression}}. > A rough design document can be found here but it needs some update. > Introduction of annotations and basic type extraction will come later: > [https://docs.google.com/document/d/1RM_-XvD25AldUOl7xRSvA3sascWBa1-Jze3i5mvb7WU/edit#heading=h.kwyjplavecx4] > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
