Actually that thread was started by 'fl'.

That's true. I'll have to do a substantial project soon. But a lot of my 
interest is about comparisons between Python and the languages I work on.

(Especially of speed. Up to now my interpreters have been comfortably 
faster. But with PyPy I might now have do do a bit more work on mine 
next year. This is where a proper application is needed for comparison 
and not small benchmarks.)

I'm also interested in what handy features I can 'borrow' from Python. 
Enough that I was planning a big upgrade earlier this year to bring it 
more into line with how Python works. (/That/ is a good way of learning 
about a language! To try and implement a lookalike.)

But that was changing my language too much (I was losing too many 
features of my own) so it was abandoned. (Perhaps it can be a separate, 
higher level language at some point as I quite like the Python style 
even if I have misgivings about some features.)

I can already tell you that I will never be able to write 'Pythonic' 
code if that is what you mean by 'decent'. But at least everyone will be 
able to understand it!
