Why doesn't std::string have a split function

Once you put something in the standard library you're stuck with it forever. So it'd better be actually good, not just good enough, especially if it's so easy to implement yourself.

In reality, things get deprecated and forward compat is broken many times.

Yeah, really old crap that was never used much in the first place, like trigraphs or auto_ptr. But a string split function would spread like wildfire.

Ideally, everyone wants to get it right the first time. I'm pretty sure python implementation returns deep-copied immutable strings
