If b and c are signals (or behaviours as they are called in Reactive)
carrying Num values of the same type, you can simply say a = b + c, and
you're done. Signal a will be updated only when either b or c is
updated. Note that this must be understood in the context of laziness,
i.e. not a single sum is calculated until a sample of a is requested.
