Probably lexical scope for anon classes would be better here, but due to
fact that proposal is to
use initializer block instead of constructor arguments, that was the reason
why initializer block
got before anon class definitions.

The examples don't show that cause it's forbidden.
There is a note on that in RFC on purpose

Using constructor arguments and object initializer would introduce noise
and you'll be potentially initializing object twice:
using object initializer block and using constructor args what may be
misleading.

Future scope mentions only about letting to create stdClass with omitting
of the class name only,
nothing said about removing a new keyword.
