I realize that I need to don some fireproof gear for suggesting this,
but I really wonder how much fallout we'd have from just allowing {} to
be used.. It's about a billion[1] times cleaner and more sensible than
using {0} and doesn't create a dependency on what the first element of
the struct is..
