FR: Matching maps with various type

[jarl-dk]

Given an actual map like this:

        Map actual = Map.of(
                "k1", Map.of(
                        "k11", "v11",
                        "k12", "v12"),
                "k2", List.of("v21", "v22"),
                "k3", "V3"
        );

I wish/expect to make an assertion with matcher that looks like this:

        assertThat(actual, AllOf.allOf(
                IsMapContaining.hasEntry("k1", AllOf.allOf(
                        IsMapContaining.hasEntry("k11", "v11"),
                        IsMapContaining.hasEntry("k12", "v12"))
                ),
                IsMapContaining.hasEntry("k2", IsIterableContainingInOrder.contains("v21","v22")),
                IsMapContaining.hasEntry("k3", "v3")
                )
        );

But this fails with

    method org.hamcrest.core.AllOf.<T>allOf(java.lang.Iterable<org.hamcrest.Matcher<? super T>>) is not applicable
      (cannot infer type-variable(s) T
        (actual and formal argument lists differ in length))
