are you talking C or D? I could have sworn that in C a "pointer to a fixed size
array" (e.i. double indirection) was written as "int[4]*". If it isn't, how is
it written?

Oh. I think I just figured it out!:

int[4] a;
int[4]* i = &a;

i points to the same point as a but has a different type *i is the same pointer
as i but with the type of a and **i is the content.

OK what I want to do is return *(&a), a type that is the same as "a" but is
mutable. 

p.s. Darn I should check the by line before I post
