#just-asking: Could the wait operand value be modelled as a type, so that we do not have to split it across three operands/attributes?

I guess we could. Operands and the attribute are mutually exclusive. The attribute is there only when there is no value in the clause. I'll have a look a that but will probably put that in a separate patch if we can change that since other op already model the wait clause this way.

@kiranchandramohan Thanks for the review. IF you have 2 minutes can you have a look at D88941. It's pretty much the same op for enter_data.
