You can also use template specialization, which, depending on your use
case, might be shorter and clearer than a static if.
template Foo(T: T[]) will specialize for dynamic array arguments. T
will be the element type (so for int[], T will be int).
template Foo(T: T[n], size_t n) will specialize for static array
arguments. T will be the element type like above, and n will be the
size of the array.
template Foo(T: T[K], K) will specialize for associative array
arguments. T will be the value type, and K will be the key type.
