Typo? If not, what is 'd'? Either way, I'd like mismatching tuple lengths to fail, not assign the tail to the last variable. Or, as pelle brought up: auto (a, b..., c) = expr, where b = expr[1..2] and you may have only one ... in the lhs.

It's all nice but as my colleague once said: put it on the todo list right after 'learn Portugese'. -- Tomek
