Hi!

Could anyone tell me if there is any example where in e.g. metaprogramming 
there is a need of strict order of declarations and definitions of templates?

Theoretically there should not be a problem, but maybe there are some tricks 
where order influence on fitting types and/or for lookup of specializations.

Generally the question is related to the fact, that GCC force user to put 
typedefs and declaration/definitions in proper order before any usage of 
types. And I am looking for the example which points why we can NOT mix all - 
when the order is important.

Regards.
