Thanks!

Reading demerphq comments I understand that the way it's going to be fixed is not decided yet. So I'll watch this space closely now :)

This seems definite:

	Any version	Before 5.12	Deterministic Behaviour	Only in 5.12+
To match [0-9]	/[0-9]/	/\d/ (sometimes) /[[:digit:]]/ (sometimes)	/\d/ (always)	/\p{PosixDigit}/
To match a Unicode Digit	/\p{Digit}/	/\d/ (sometimes) /[[:digit:]]/ (sometimes)

I don't know what's going to happen to /[[:digit:]]/.

It's not clear (if it's been decided) if the deterministic behaviour will be active by default in 5.12+, or if a pragma (use 5.012;) will activiate it.

If the deterministic behaviour will be active by default in 5.12+, there may be a pragma to deactivate it.
