Any particular reason why it isn’t used starting 4.14, the current LTS? Just curious, I don’t currently depend on containers (although I do depend on many libraries of yours).
Ha! I was under the mistaken impression it was introduced in 5.1. I
think it’s because it’s in 5.1 that this attribute started being used in
the stdlib. I’ll correct that in the next release, thanks for the
shoutout
