And who tells me that you'll not need to change your mind again in 2020?

If there's a reliable, repeatable benchmark showing Rakudo can sustainably outperform Perl in the large, I'll change my mind. "Slower than Ruby parsing log files" suggests that's unlikely to happen.

YOU convinced me back then with the argument that Perl 5's inner workings have become unmaintainable and Perl 6 will be much easier to work with.

XS is still a hazard, but I didn't count on Perl adopting a yearly release cycle.
