printf "%{" is legal, and prints %{. With warnings on, it does issue a warning, but it's (currently) not illegal.

But your initial proposal talked about interpolating in strings, and in strings, "%{hash}" is currently fine. No warnings. I'd be more worried about regular strings 'breaking' than any (s)printf formats.

    As far as I know, none of the new extensions in 5.10 are enabled unless a switch or pragma is used, so old code can continue untouched.

    The point about %{} is that it is a fairly natural extension of existing mechanisms that doesn't conflict with existing uses. That there may exist by happenstance some code that would need to be changed in minor ways before it would run under the auspices of the feature pragma is not, (should not be), a barrier to the addition of new features.


    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

    In the absence of evidence, opinion is indistinguishable from prejudice.
