In my view, we should not use the pragma to hide the warning messages -- we should remove use of the experimental constructs, including the smartmatch operator. There have already been a couple recent-ish patches pushed [1] to remove uses of smartmatch. This is because, as the link you included in your email states, features that the Perl developers have marked as experimental are subject to change, which could lead to surprises as future versions of Perl get released. I have opened a new bug [2] for removing the remaining uses of the smartmatch operator, and I suggest that we add a new coding guideline to this effect: === PERL19: The use of the Perl smartmatch operator is forbidden === The Perl smartmatch operator, including ~~ and given/when, has been [http://perldoc.perl.org/5.18.0/perldelta.html#The-smartmatch-family-of-features-are-now-experimental marked experimental] as of Perl 5.18.0. Since the meaning of the smartmatch operator is subject to change, and since using it will by default add warnings to the error log, new code should not use it.
