-Subject: [PATCH] Adapt to Perl 5.36
-
-A developmental release of Perl 5.36.0 fails to run tests with:
-
-    $ perl -Ilib t/basic-misc.t
-    1..72
-    Can't modify undef operator in scalar assignment at lib/Biber/Section.pm line 433, near "undef;"
-    Compilation failed in require at lib/Biber.pm line 24.
-    BEGIN failed--compilation aborted at lib/Biber.pm line 24.
-    Compilation failed in require at t/basic-misc.t line 11.
-    BEGIN failed--compilation aborted at t/basic-misc.t line 11.
-    # Looks like your test exited with 255 before it could output anything.
-
-This is because of a missing semicolon between commands in
-del_everykeys(). The new perl is more strict and raises a compile-time
-error:
-
-    $ perl -e '$a = undef $b = undef;'
-    Can't modify undef operator in scalar assignment at -e line 1, near "undef;"
-    Execution of -e aborted due to compilation errors.
