Test your code at least on the minimum and maximum version of Perl you want to support (and if you want to be thorough, the ones in between too). You can easily have different Perl versions installed on your system. See for example perlbrew. If by "downgrade" you mean by some kind of option to make a newer Perl behave like an older one, then no, at least not completely: While you can disable features, that won't disable all of the things that the newer Perl supports. Only actually using the older Perl version will give you reliable test results.	[reply]

None that I'm aware of (though I'm hardly the most experienced monk in the Monastery, so maybe one of the senior brothers will enlighten me). You'll just have to be careful.	[reply]

Just look for deprecation warnings. Perl is excellent at backward compatibility, but if a feature is marked "experimental" or deprecation warnings start appearing, then you might want to pay good attention and refactor your code that relies on these. You can also always, test against blead.	[reply]
