It's not quite so simple. Consider for example:
struct Foo { int bar; }
struct Oof { int bar; }
void process(Foo foo) { }
void process(Oof oof) { formatDisk(); }
void main() {
process({bar : 5}); // which overload should get called?
}
As for `Foo({bar : 5})`, that's just wrong syntax. Just write `Foo(5)`
and it will work.
