The
Setfunction was added to the interpreter with a small oversight:AllowedWithinNondeterministicOperationOrdershould have been set to false, as it is forClearandClearCollect, and asSetin Canvas apps. Because of this, it is possible to writeForAll( foo, Set( foo, [1,2,3] ) )and create self-modifying iterations.To fix this introduces a breaking change to Power Fx V1. A new feature
