Test case
-----------------------
class C6293 {
    int token;
}
struct S6293 {
    const(C6293)[] tokens;
    void f() const pure {
        const(C6293) a = tokens[0];
        int b = a.token;           // <-- separating it is ok.
        int c = tokens[0].token;   // <-- cannot access mutable data 'token'
    }
}
-----------------------
x.d(9): Error: pure nested function 'f' cannot access mutable data 'token'
-----------------------

If that 'b' can be accessed in a 'pure' function, there's no reason 'c' cannot.
