If you change the return type to a void* your code basically
works.
void* makeMultidimensionalArray(T, Allocator)(auto ref
Allocator alloc, size_t[] lengths)
{
if (lengths.length == 1)
{
int x = 0x01FEEF01;
return cast(void*)makeArray!T(alloc, lengths[0], x);
}
else
{
alias E = typeof(makeMultidimensionalArray!T(alloc,
lengths[1..$]));
auto ret = makeArray!E(alloc, lengths[0]);
foreach (ref e; ret)
e = makeMultidimensionalArray!T(alloc,
lengths[1..$]);
return cast(void*)ret;
}
}
The problem is that then you need to cast back and that
essentially results in the original problem. Can be done but
probably gonna have to use string mixins.
That isn't a solution and will probably introduce other bugs.
As soon as you have to result to using void* is an indication of
bad design IMO, because it leads to very unsafe possibilities.
