%Module::CoreList::deprecated is a map from versions to modules "deprecated" in that version of perl. Every perl version has a full list, meaning we get entries like this: 5.011001 => { 'Class::ISA' => '1', 'Pod::Plainer' => '1', 'Shell' => '1', 'Switch' => '1', }, 5.011002 => { 'Class::ISA' => '1', 'Pod::Plainer' => '1', 'Shell' => '1', 'Switch' => '1', }, For later versions with more deprecations, this gets pretty big. More importantly, it needs to be updated versionly. Each perl version should instead be a delta so we only need to add additions or removals when they occur. We already have code for this, used by Module::Corelist: Module::CoreList::TieHashDelta Module::CoreList::deprecated should be set up with a delta hash. -- rjbs

This hash tracks core module deprecations, which becomes very verbose if listing out the deprecated modules for every perl version. Instead, we can track the delta for each release, using Module::CoreList::TieHashDelta to inflate as needed.

Thanks, Mike! We discussed this on IRC, and for the record: it seems like this will never reset the contents as it should. For example, 5.013001 should have one entry, but this code makes it look like it will have quite a few more, including everything from 5.012005 as well. When I tried to test this, things got a bit odd: IN BLEAD: DB<11> x $Module::CoreList::deprecated{'5.013001'} 0 HASH(0x7fa5dd042c18) 'Shell' => 1 WITH THE PATCH: DB<5> x $Module::CoreList::deprecated{'5.013001'} 0 HASH(0x7fc043f9ec48) empty hash Mike said he'd investigate. -- rjbs

Thanks, applied as 5ff416f I applies some more work on top of that to bring in an omission that had been fixed between your patch and later blead. I also updated Porting/ so that updating the corelist file will create new delta-style entries instead of bulk updates. Testing this by hand worked okay.
