Similar case here; the 'varargs' end up in a GC-allocated array. 
I've recently changed `scope` slice params, so that array literal 
arguments are allocated on the caller's stack instead; so adding 
`scope` for these variadics *should* probably do the same:

void tester(Test test, scope Test[] tests...);
