You need Thiago Adam's struct member defaults to go with it.

(This might tick a box but it's generally unwieldy compared to the real 
thing. However, when they added designated initialisers, they could have 
introduced named parameters at the same time.)

They're not absolutely needed.  Any omitted members default to zero.
You can often (but not always) arrange for that to be a meaningful
default value.
