Every programming language has its standard library of containers, algorithms, and other helpful stuff. With languages like C#, Java, and Python, it's practically inconceivable to use the language without its standard lib.

Yet, on many C++ games I've worked on, we either didn't use the STL at all, used a tiny fraction of it, or used our own implementation. It's hard to tell if that was a sound decision for our games, or one simply made out of ignorance of the STL.

So... is the STL a good fit or not?
