This should work:

Drepl: static assert: `is(int == (int))` is false

That will only work for type tuples. We need a general solution
that would work for any alias tuple.

split gives you a newly allocated array with the results, splitter is lazy equivalent and doesn't
allocate. Feel free using either, doesn't matter much with these small puzzle

splitter() is a lazy range algorithm. split() is a range algorithm as
well but it is eager; it will put the results in an array that it
