Pandoc::Filter::Lazy

  my $filter = Pandoc::Filter::Lazy->new(
      'Header => sub { Header $_->level, [ Str $_->string ] }'
  );
  if ( $filter->error ) {
      say STDERR $lazy->error;
      say STDERR $lazy->code;
  } else {
      $filter->apply(...)
  }

This module helps creation of Pandoc::Filter with arguments given as string. 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 }

In addition to the methods inherited from Pandoc::Filter:

This module is used in command line scripts pandocwalk and pod2pandoc.
