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
