In the about his event the language would not permit side-outcomes in expressions (prevalent in functional languages), then the purchase of evaluation has no value semantics—while it may nonetheless bear on regardless of whether an infinite recursion terminates, or have other overall performance implications (within a useful language with match expressions, small-circuit analysis is inherent, and organic takes advantage of with the ternary operator come up considerably less normally, so this stage is of constrained concern).
