And small things. Like your function wants to know if a parameter was not used when calling it. The ideom if par=None breaks if called with arrays. Ending scripts with a command early would also be great (for interactive programming)

Also what is wrong in having a switch statement? (I`d like one with range cases 1<x<10..)

Accesing dicts with a struct syntax.

'Inline' C functions.

JIT, especially for loop acceleration.
