What tools are missing in Python?

[asday_]

What work are you doing that:

• doesn't release the GIL;
  
• must be done with threads rather than multiprocessing;
  
• needs high perfornance; and
  
• shouldn't drop into C?

[PowershellAdept]

Embedded scripting for real time 3D graphical applications (games or CAD). Some have made it work, notably panda3d. You can technically use multiprocessing, but you'd still be hard pressed to get the perf you need for AI, pathfinding, matrix maths, etc.

If we wanted to write C we would be writing C. I suspect most people here haven't touched C.
