=head1 NAME

Catmandu::Fix::set_field - add or change the value of a HASH key or ARRAY index

=head1 DESCRIPTION

Contrary to C<add_field>, this will not create the intermediate structures
if they are missing.

=head1 SYNOPSIS

   # Change the value of 'foo' to 'bar 123'
   set_field(foo, 'bar 123')

   # Change a deeply nested key
   set_field(my.deep.nested.key, hi)

   # If the second argument is omitted the field has a null value
   add_field(foo)
