Well a bit more compile time isn't the end of the world, and by 
far not the only metric (e.g. readability and maintainability 
also rank high). You're slightly obsessed with the template 
compile-time topic ;).

BTW, the term expensive is fairly subjective easily 
misunderstood. Sth. more specific would reduce the chance for 
confusion, e.g. "tuple map and array require longer to compile"
