Yes, but certainly simple parameter pack expansion shouldn't be
this brittle. I want to be able to write:
foo(getArray(v)[]...); // v is a parameter pack (1, 2, 3)
And be confident in that it gets simply re-written as:
foo(getArray(v[0])[], getArray(v[1])[], getArray(v[2])[]);
It's easy to conceptualise and easy to get it right.
