DESCRIPTION

The following should result in equivalent filters: Pandoc::Walker::action( ... ); # ... as code Pandoc::Filter::Lazy->new( '...' ) # '...' as string The script passed as only argument is tried to convert to valid Perl by escaping selectors and adding a missing "sub { ... }"", for instance Code|CodeBlock => say $_->class Is converted to 'Code|CodeBlock' => sub { say $_->class }
