But expressions that use unsafePerformIO might get inlined. > CSE is no problem either, it even helps if it's performed (and it is > with optimisations turned on), since it results in smaller equivalent > networks What about evaluation time? If I remember correctly, the values of signals depend on the time when the signal expressions are evaluated. So evaluating them multiple times might lead to different behavior.

But in contrast to ordinary values, you have an internal mutable state, don’t you?
