A tail calling interpreter for Python (already landed in CPython)

Will Python ever get fast? Or even _reasonably_ fast?

The answer is no, it will not. Instead they'll just keep adding more and more syntax. And more and more ways to do the same old things. And they'll say that if you want "fast" then write a native module that we can import and use.

So then what's the point? Is Python really just a glue language like all the rest?

Python is fast enough for a whole set of problems AND it is a pretty, easy to read and write language. I do think it can probably hit pause on adding more syntax but at least everything it adds is backwards compatible. You won’t be writing a 3D FPS game engine in Python but you definitely can do a whole lot of real time data processing, batch processing, scientific computing, web and native applications, etc. before you need to start considering a faster interpreter.

If your only metric for a language is speed then nothing really beats hand crafted assembly. All this memory safety at runtime is just overhead. If you also consider language ergonomics, Python suddenly is not a bad choice at all.

While Eve Online isn’t an FPS, it is an MMORPG written in stackless Python, and seems to be doing OK.
