So when you use local variables in a delegate, the compiler
usually makes a copy of them

make the delegate in opApply scope

Can't `opApply` with `auto` return type works since it infers
attributes ?
I think the problem is that the delegate which is required by
opApply is allocated using the GC.
Is there any way to make opApply @nogc? or provide the same
foreach functionality without implementing a range interface?
I want to iterate over a piece of memory using a pointer. I
thought about using opSlice but that doesn't provide information
for an index in a foreach loop.
auto
When compiling, what exactly does the -betterC flag do? The
command help says "omit generating some runtime information and
helper functions" but what does this really mean? Is there any
specifics somewhere?

A more correct example:
import core.stdc.stdlib;
import std.traits;
ref T foo(T)()
{
alias Type = Unqual!(T);
Type* foo = cast(Type*) malloc(Type.sizeof * 8);
return *foo;
}
void main(string[]
In the following code, the `foo` function doesn't work when
casting to an immutable or shared type. Can anyone please explain
what is happening here? Is there any way of returning such
variables byRef from a malloc'd chunk of memory?
import core.stdc.stdlib;
ref T foo(T)()
{
int* foo
I've tried the following code and I get the error:
Error: template Foo(A) does not have property 'of'
struct Foo(A)
{
private int _foo;
@disable this();
public this(int foo)
{
this._foo = foo;
}
public static auto of(B)()
