Look, it's been a long day, and I've got a toothache, and I ate too many
pierogies, so accept this as possibly deeply confused thinking, but I'm not
sure I see a problem with this.
Paul isn't talking about changing what "use strict;" does. We'd leave that
doing the same thing as "use strict ':5.8'". There would be "use strict
':5.22'" that also includes "use strict 'time'". Maybe we'd go nuts and say
that the "use strict" implied by "use v5.22.0" is the versioned one.
The other thing we can't do without opening a can of worms, I think, is "use
strict ':latest'", because even if strictures are always safely addative, when
you need to say, later, "no strict 'time'" but only on the right versions,
you're in a weird place.
Somebody set me straight, if I'm just too full of ... potatoes.
