A function used to compare the new value of a signal with the previous
value when the signal's value updates. If the function returns false,
this will cause the signal's dependencies to update themselves with the
new value, because the value is considered to have changed. If the
function returns true, dependencies will not be updated, because no
change is considered to have occurred.
