import std.bigint;
struct Foo {
    BigInt x;
    void bar() { x++; }
}
void main() {}


DMD 2.052 shows:

It's nothing to do with BigInt. Here's a reduced test case:

struct Bug5810 {
    void opUnary(string op)()    { }
}

struct Foo {
    Bug5810 x;
    void bar() { x++; }
}

test2.d(13): Error: var has no effect in expression (__pitmp4)
