I've just finished reading C++ Template Metaprogramming again. I just don't get it.

Why would someone use a type container?

Imagine a case where for some reason you would like to call

register();

for all combinations of X1..Xm and Y1..Yn. Writing the calls by hand gets tedious. If you put Xi and Yi in type sequences, you can write a metaprogram that generates the calls.

I have to say this is probably the most convincing example I've seen since the last time I read that tutorial thing about representing physical quantities. -- Pedro Lamarão
