Why should anonymous types cannot be passed around methods?

Question

What is the design decision to lean towards not returning an anonymous types from a method?

Answer 1

A lot of answers heere seem to indicatie that it is not possible because of the current syntax and rule. But the question is about changing them. I think it would be possible, but a little complicated and resulting in an awkward (error-prone) syntax. Like

var f() { return new { A = "*", B = 1 }; }

var x = f();

The question is whether this adds sufficient value to the language to make it worth it.
