[boost] Re: [mpl]mpl::plus and non Integral Constants

Andy Little writes:

Reading the mpl documentation it states that boost::mpl::plus is expected to be specialised for non Integral Constants.

Therefore should the following work ?:

typedef boost::mpl::plus<int,int>::type int_plus_int_type; // eg int presumably

OTOH it could be said that:

mpl::plus<int_<1>, int_<1> >::type

and

mpl::plus<int,int>::type

are conceptually different and that therefore mpl::plus<int,int> should be(remain) invalid.

Any thoughts?

I'm strongly in favor of the latter premise. -- Aleksey Gurtovoy MetaCommunications Engineering
