[boost] program_options: Support for open-end options

Hi, It would be great to implement support for open-end options, something like that: item_1 = 23 item_2 = 45 ... item_N = 465 The idea is to to be able to provide following input: configOptions.add_options() ("item_", value<int>(), "items"); now if add_options() sees a key that ends with a "_" it accepts all options with keys that start with item_, no matter what comes after it, and treat all of them as int . Nesting should also be possible - like this: "item_.subitem_.subsubitem_" (item_3.subitem_FOO.subsubitem_34 should be a valid option key). I can try to implement it, however only if it will have a chance to be merged into the boost library. Whom should I contact regarding this? Thank you, Simone
