Thanks, I was going to ask Algis that same question.

But still, is this solution really faster or better than the one using
list comprehension and the expression 'x*x'?
It seems to me that the above solution (using hypot) involves repeated
square roots (with subsequent squaring).

Best regards,
Gabriel.
