C++ Executors That Never Arrive

Executors An executor provides one or more execution functions for creating a callable. Name Cardinality Direction Standard execute single oneway C++20 C++23 twoway_execute single twoway C++23 then_execute single then C++23 bulk_execute bulk oneway C++20 C++23 bulk_twoway_execute bulk twoway C++23 bulk_then_execute bulk then C++23 Cardinality: Creation of one execution agent or a group of execution agents. Direction: Directions of the execution.

A photographed presentation slide lists C++ executor functions and their planned standards, with C++20 crossed out for some entries while C++23 remains. The joke is that the promised executor features keep being postponed, leaving programmers to build their own workarounds. It is sent as a reaction to delayed language features and overambitious standards roadmaps.
