I worry that Python has been adding too many complex features too quickly.  
But then, I suppose you don't have to use them.

Ah, Lua!  I think I last tried it back before I had even encountered  
Python, but back then I didn't really have a need for it. Maybe I should 
revisit it.  I would want at least some equivalent for numpy and a gui 
system like Qt.  I gather that wxWindows is a possibility among others.

Like you, I thought those plans call for a lot of work, and completion 
might be some time off. Part of that might be the ever-growing complexity 
of Python3, which is accruing features that cannot be implemented simply, 
thereby complicating maintenance of minority implementations such as Jython 
and IronPython. 

I greatly admire the tasteful engineering that I see in the choices that 
Guido van Rossum made in earlier releases. For example, an operating system 
that supports multi-tasking well relieves the need for multi-threading. 

For more straightforward scripting engine uses, there's always Lua, though the 
fork of Lua done to implement a JIT  trails the main 
implementation . There is an interesting offshoot of 
the language that is aimed at systems programming . 

Yeah, yeah, I know, I'm wandering far afield, sorry for trespassing. I'll 
come quietly, officer!
