Just by guessing, what we don't see here is that there is a
wrapping layer that does the copying. Disposal logic is called
by that layer. So, your scope(exit) takes place at a higher
layer. Here is made-up-pseudo-code by me. :)
TypeForExcel wrapper_actually_called_by_excel(/* ... */) {
/* ... */
double[] ret_from_your_function = FuncReturnArrayNoGc(/*
... */);
scope (exit) disposal_function(ret_from_your_function);
TypeForExcel arg_to_excel =
copy_for_excel(ret_from_your_function);
return arg_to_excel;
}

Yep, that's pretty much what happens, except that the
`scope(exit)` is inside a `static if` that checks for the
presence of `@Dispose`.
