Hi Gil,
Awesome work :) it took me a while to understand that you also
committed tests along with the refactoring. For the future I recommend
mentioning this somewhere in the commit log for easy review. Also,
perhaps as a further improvement you might want to rename the tStream
variable into something more meaningful. The variable name might be a
bit vague.

Hello Taher !
I'll be a little bit more verbose in commit log next times :), and for
the tStream, it was a miss, i'll fix it soon.
Thanks as always for your review !
