+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.
