'scope' confusion

[Walter Bright]

The trouble here is the scope array is a static array. This means the scope 
applies to the elements of the static array.

But when passing it to the function, the static array is converted to a dynamic 
array. A dynamic array is a pointer to the array's elements.

The scope protections are not transitive, so a scope dynamic array does not 
protect its elements as scope, hence the errors you're seeing.
