Unfortunately, reversing args to airs_nam_ti1_3_t CTOR, as in:
pairs_nam_ti1_3_t pairs_nam_ti1_3_v ( fusion::pair<mpl::int_<2>,ti<2> >(2) , fusion::pair<mpl::int_<1>,ti<1> >(1) )
causes compile error about "no matching function".
Investigating.
Problem solved By adding a templated member function, put, to pairs_named template. Also, renamed overloaded arg function to at_key, since that's more descriptive.

BTW, just read:
http://www.boost.org/doc/libs/1_44_0/libs/fusion/doc/html /fusion/notes.html#fusion.notes.overloaded_functions
which says:
There is an overloaded function, f(k), for each key type k. The compiler chooses the appropriate function given a key, k.
which is exactly the method used in named_component_ctor.cpp, where the overloaded function is arg.
It's not obvious to me, after looking at: key_of_impl.hpp value_of_impl.hpp in boost/fusion/container/map/detail where this overloaded function, f, is located. (Of course I assume it's not named f, but something like value_of...). Could someone point it out? TIA. -Larry
