There are more CPAN distributions affected with similar error messages ("Couldn't find declarator ..."): * App-Lingua-BO-Wylie-Transliteration-0.1.0 : Error: Couldn't find declarator 'method' * CFOUTS/DateTime-Format-EraLegis-0.011.tar.gz : Error: Couldn't find declarator 'method' * CSSON/Dist-Zilla-Plugin-MapMetro-MakeLinePod-0.1202.tar.gz : Couldn't find declarator 'qqi' * CSSON/OpenGbg-0.1404.tar.gz : Couldn't find declarator 'qs' * TOBYINK/PerlX-QuoteOperator-Inescapable-0.002.tar.gz : Couldn't find declarator 'Q' There are two further with different error messages: * EXODIST/Test2-Plugin-SpecDeclare-0.000003.tar.gz : Useless use of numeric gt (>) in void context * WKI/Catalyst-View-ByCode-0.28.tar.gz : died: Can't use an undefined value as a subroutine reference

This happens also with stable Devel-Declare-0.006022

My testing came to a different conclusion than the subject line indicates. According to my tests it was not 0.006_021 that broke these eight distros but 0.006_020. I smoked 8 perls, two of each of 5.28.2, 5.30.2, 5.31.3, 5.31.4 against each of the 8 distros covered in this issue. That lead to 64 tests, 32 against ETHER/Devel-Declare-0.006019.tar.gz and 32 against ETHER/Devel-Declare-0.006_020.tar.gz. The former 32 passed, the latter 32 failed. The finding suggests that 0.006_020 broke MSCHWERN/perl5i-v2.13.2.tar.gz and seven other distros. That notwithstanding, 021 was released as 022 four months after this issue was openend, so it's a minor scholastic question what broke what when exacty.

None of this is surprising. There were only very minor changes in 021 (fixing a compiler warning and adding ppport.h) and none at all in 022. The work done to fix DD for changes made to the parser in blead all appeared in 020. I hope no one is waiting for bated breath for a fix, because none is on the horizon. Karl Williamson graciously provided the fix in 020 and advises that it is not straightforward to fix the remaining issues that the other modules are experiencing, and I am not familiar with this area at all. What Devel::Declare is doing in the parser is highly fragile and it's a miracle things have held together this far. This fragility is exactly why there are now much better hooks into the parser to achieve similar goals -- namely PL_keyword_plugin (see perldoc perlapi). Syntax::Keyword::Try (and other projects by Paul Evans) are good places to look for modern examples of its use.
