Simple Trie Implementation in C++11

I think auto won't have any run-time performance since type deduction happens at compile-time.

I'm already well aware of this. I'm asking why the OP thinks otherwise. It's not outright impossible to make it affect performance [1] but I'm trying to see what the concern is.

[1] Like by taking the approach that results in a cast, e.g. here: https://news.ycombinator.com/item?id=20493263

Oh, I see. I didn't know that type deduction happens at compile-time :o

Yeah, that's how type systems work in most languages. That's why we have them: they prevent mistakes before you even run your code :)
