This solution assumes the two sets are of equal size; what if we
don't have such assumption? i.e. we only know the two sets
divided into two logical groups.
I've tried something like this: the AliasSeq specify the logical
printRandomElemAddr(AliasSeq!(extraA, extraB, extraC, extraD),
a, b, c);
but cannot make it work.
(I'm asking for a more general solution, e.g. what if we have 3,
or N sets of variadic parameters?)
Looks like we can only pass 1 variadic parameters, then the
question is what's the best way to divide it?
Is there any special marker (variable or type?) can be used to
divide? and what's the staticSplit?
