I think a lot of confusion has resulted from people, including myself,
thinking that mpl::type_list and loki::type_list are (or should be) the
same thing. Both have advantages and disadvantages.
If mpl and loki are to be integrated it is loki::type_list and
mpl::list_node that need to be merged.
loki::type_list could be renamed to type_list_node.
Then mpl list_node could be split into type_list_node and value_list_node
(reducing the number of template args from 4 to 2).
This would leave us with
mpl::type_list == loki::TYPE_LIST_NN
mpl::type_list_node == loki::type_list_node
This will have some implications. Here are the ones I can see
* To use a mpl::type_list with a loki class you will have to use ::type
eg. mpl::type_list< int, float >::type
This problem should go away once template typedefs are available.
* To use other mpl containers with loki you will need to convert them (I
assume this is a common requirement with a simple solution).
