This compiles:
f(() => null);


This causes no assert to fire:
foo(() => (int[]).init);


While this doesn't even compile:
foo(() => []);

Error: function test.foo (int[] function() del) is not callable using argument
types (void[] function() pure nothrow @safe)

Since lot of time in D dynamic arrays are not pointers, so generally accepting
"null" as empty array literal is a wrong design decision, especially since the
"[]" literal is available.
