Struct initialization using member syntax without variable

To initialize a struct with the member names a variable is required.
Example:
struct Foo
{
int a;
int b;
}
Foo foo = { a: 3, b: 4 };
That's a bit annoying when you want to pass the struct to a function or
return it.
Foo bar()
{
return { a: 3, b: 4 }; // error
}
void bar(Foo foo);
bar({ a: 3, b: 4 }); // error
Is there any reason for this limitation? I guess it will make function
overloading more difficult, but that could easily be solved with the
following syntax:
bar(Foo{ a: 3, b: 4 });
Or this:
bar(Foo(a: 3, b: 4));
This would also allow one to use "auto" when declaring a variable:
auto foo = Foo{ a: 3, b: 4 };
