struct S{
enum n=1;
}
struct T{
static n=1;
}
void foo(S v)@nogc{
auto f=()=>v.n; // error
}
void bar(T v)@nogc{
auto f=()=>v.n; // error
}
This code should compile.

To add to this, consider the following code:
import std.algorithm;
struct Foo
{
static int fun(int n)
{
return n + 1;
}
}
void main()
{
int[10] arr;
Foo foo;
arr[].map!(n => foo.fun(n));
}
the line
arr[].map!(n => foo.fun(n));
causes GC allocation, whereas the same line with foo replaced with its type
arr[].map!(n => Foo.fun(n));
does not. This is despite the functionality being absolutely identical as fun has no dependency on 'this' whatsoever due to being a static member.
