NAME

       Catmandu::Fix::Builder - Base role for Catmandu fixes

DESCRIPTION

       This role expects a "_build_fixer" method that produces a coderef that transforms the
       data.  Used in combination with Catmandu::Path implementations, data manipulations can be
       described in a relatively high-level way. Most fixes shipped with Catmandu work this way
       and can be used as a starting point to write your own fixes.

SYNOPSIS

           package Catmandu::Fix::my_fix;

           use Catmandu::Sane;
           use Moo;

           with 'Catmandu::Fix::Builder';

           sub _build_fixer {
               sub {
                   my ($data) = @_;
                   $data->{foo} = 'bar';
                   $data;
               }
           }
