Bug

Using CC 1.0.3:

using System.Linq;
class Foo
{
    void M()
    {
        var xs = new System.Collections.Generic.List<int>();
        xs.Select(x => Func<int>(x));
    }
    object Func<T>(object x) => x;
}

After apply suggesting fix, got CS0123 No overload for 'Foo.Func<int>(object)' matches delegate 'Func<int, object>'

We should not offer a diagnostic in this situation.

Bug confirmed. I evolved the description to one that was independent of a specific library.
