[Proposal] Sometimes a collection initializer can be enough

Suppose we have this code:
```VB.NET
Call Foo(
New List(Of Integer) From {1, 2},
New List(Of String) From {"x", "y"}
)
```

Wouldn't it be nice if we just rewrite it as:
```VB.NET
Call Foo(From {1, 2}, From {"x", "y"})
```

and the compiler infers the type from the param [or var] types, so it can lower the second compact form to the first verbose form?
