actually, may be someone want to compare with int, and it would always false. which is hard to debug later. but don't know how to better fix it.

Thanks!

I think there's actually a compiler bug involving enums and the self restriction, but for now let's fix this particular bug :-)

Fix self restriction with including generic module
090fa27 
Ref: crystal-lang#3847

Now, we can get a compile error with such a code:

    module Foo(T)
      def foo(x : T)
        x
      end
    end

    abstract struct Bar
      include Foo(self)
    end

    struct Baz1 < Bar
    end

    struct Baz2 < Bar
    end

    Baz1.new.foo Baz2.new # => no overload matches 'Baz1#foo' with type Baz2

This commit adds `lazy_self` parameter to `lookup_type`. When `lazy_self`
is `true`, `lookup_type` keeps `self` in generics type. It is used to
look up type for `include` and `extend`.
