Parameter: Check `TimeDependency` policy is well handled everywhere
In several operator definitions the trait type define set it as None
; I'm not sure that is what was intended (and as time dependency was introduced after most operators it might have been a convenient first step in implementation).
At any rate, even if my suspicions are right it's not a bug per se: it simply means that the operators are less generic than they could be (passing a Parameter
with a time dependency would yield a compilation error).
As in #1852 (closed) I make all the operators with Parameter
template ones it is easy to fix if my first impression given here is right.
