Initialisation style impact json result

[aminiussi]

I was surprised to see that switching between assignment initialization and aggregate initialization added an array layer to the parsed json.
Is that intended ?

Thanks

It's not "intended" but is "expected" and varies by compiler. It is the very first item in the FAQ.
