Description:
------------
In the 'new' operator syntax description (https://github.com/php/php-langspec/blob/master/spec/10-expressions.md#the-new-operator):

object-creation-expression:
    new  class-type-designator

class-type-designator:
    qualified-name
    expression

expression links to https://github.com/php/php-langspec/blob/master/spec/10-expressions.md#general-6, which is:

expression:
    yield-expression
    include-expression
    include-once-expression
    require-expression
    require-once-expression

This is wrong. I think it should be:

class-type-designator:
    qualified-name
    variable-name
