Re: [RFC] [DISCUSSION] Compact Object Property Assignment

I don't think it's conflicting _if you insist on brackets_ after the new expression. PHP Parser grammar for "new" expressions is T_NEW class_name_reference ctor_arguments If you allowed the shorter syntax, ctor_arguments would allow an object_properties entry. I'm sure Nikita could clarify, though.
