Yes, but all we have is a passing mention of it in the FAQ. If someone 
could actually find the full content of the study and show that it is 
[still] relevant to Python, I'd give it a lot of weight too. As it 
stands, I've become far too jaded by so-called "studies" (both technical 
and medical) to accept them on blind faith.

True enough. Although, I have to ask how many times you define a new 
function only to have Python spit a syntax error out at you saying that 
you forgot a colon. It happens to me all the time. (Usually after an 
"else") If you'd never notice that the colon was missing if the compiler 
didn't point it out, is it really that readable? For me, I tend to get 
annoyed at language "features" that I'm constantly tripping over.
