How about in general forbidding lambda statements that aren't called
or used anywhere?

How?

int main()
{
    int a;
    auto b = ()=>{a++;};
    b();
    assert(a==1);
    return 0;
}

This lambda is both used in an assignment, and called.

If I do this:

10;

It's flagged as not having any effect. Similarly if I do:

() => 5;

Then it's not used/called. What is the point?
