The advantage of anonymous structs is that they can be declared in

void foo ({ int x, int y } point)

At the first look it seems interesting, but imagine that you need to
change one type or add more members to that struct, have you imagined
the mess to change all those declarations?
If you add a new member to the anonymous struct declared in "foo" any
existing call will still match. That's just like the current initializer
syntax works:
struct Bar
{
int a;
int b;
}
Bar bar = { b: }; // "a" is default initialized
If you remove a member from the anonymous struct declared in "foo" you
will get a compile error since there will be a member that doesn't match.
Because that case I prefer the old way:
void foo(MyPointStruct point)
{
}
Any changing in "MyPointStruct" will be consumed by all the code.
I'm not sure I see the difference compared with the anonymous struct.
