Not being able to specify this interferes with how I'd like to 
define my method overloads. What's the best way to achieve what 
I'm looking for?

I don't really know what you're looking for. But you need to drop 
the if condition - you can only specify them for templates as 
instantiation constraints. You may want to use a runtime check 
instead (the slice's size isn't available at compile-time - 
although it's known at the call site):

void test(int[] ints...] { assert(ints); ... }
