Catmandu::Fix::Condition::SimpleCompareTest - Base class to ease the construction of compare conditionals
=head1 SYNOPSIS
package Catmandu::Fix::Condition::has_equal_type
use Catmandu::Sane;
use Moo;
use Catmandu::Fix::Has;
has path => (fix_arg => 1);
has path2 => (fix_arg => 1);

}
1;
# Now you can write in your fixes
has_equal_type(my_field_1,my_field_2) # True when my_field_1 and my_field_2 have
# the same refence type (both scalas, arrays, hashes)
