I find it very clear and nice to read (much nicer than the MPL code), 
except for that final tuple_t to _tuple conversion.

I had to read through the documentation to understand this bit, though I 
suppose something like a transform with [](auto t) { return 
make<typename decltype(t)::type>(); } would have worked too?
