[Moved to DR at the November, 2014 meeting.]

Proposed resolution (February, 2014):
Change the grammar in 11.9.3 [class.base.init] paragraph 1 as follows:
-
mem-initializer-list:
-
mem-initializer ...opt
mem-initializer-list , mem-initializer ...opt
Date: 2013-09-16.00:00:00
The grammar for mem-initializer-list in 11.9.3 [class.base.init] paragraph 1 (after the resolution of issue 1649) is right-recursive:
-
mem-initializer-list:
-
mem-initializer ...opt
mem-initializer ...opt , mem-initializer-list
In general, however, such lists elsewhere in the Standard are described using a left-recursive grammar, e.g., for initializer-list in 9.5 [dcl.init] paragraph 1:
-
initializer-list:
-
initializer-clause ...opt
initializer-list , initializer-clause ...opt
It would be better to be consistent in the definition of mem-initializer-list.
