Item8765: "use base qw(Somepackage);" shall not be used
the use base was only intended to work alongside use fields.
perl 5.10 introduces parent.pm to fill the gap, but the safe way is to:
our @ISA qw( Module );
Globally and manually fixing all .pm files.
perl -i -ple's/^([^#]*)use base +qw\( *(\S+) *\);/$1use $2;\n$1our \@ISA = qw( $2 );/'
+ manually checked all differences.

Please note that mostly the only difference is that use base is evaluated at compile time, whereas our @ISA is done at runtime, which can cause issues in BEGIN blocks (but I've checked them all and fixed them where needed).
