Lisp mentality vs. Python mentality

[namekuseijin]

That was amusing, but that's not a question of Lisp vs Python 
programmers, just one of fun vs practicality.  Mark Tarver is the 
implementor of Qi, a higher order Lisp of sorts.  He's writing a 
compiler from Qi to Python and was learning Python along the way.

He's having fun with it, not writing it to meet a deadline.  Who never 
reimplemented things for the sheer fun of it?  The fun of writing it to 
top the current implementation, to learn how it works or merely as 
example to fellow programmers?

Oh, I know who never did it:  programmers who are into programming only 
for the paycheck and who otherwise think it's a bore.
