How can I efficiently select a Standard Library container in C++11?
...
Not that I know of, however it can be done textually I guess. Also, the chart is slightly off, because list is not such a good container in general, and neither is forward_list. Both lists are very specialized containers for niche applications.

And a last one that's even more confusing, but more flexible and wastes fewer cycles:
o = [('a'..'z'), ('A'..'Z')].map(&:to_a).flatten
string = (0...50).map { o[rand(o.length)] }.join
