.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module is a subclass of autobox that provides
List::Objects::WithUtils methods for native \s-1ARRAY\s0 and \s-1HASH\s0 types; you can
treat native Perl list references as if they were
List::Objects::WithUtils::Array or List::Objects::WithUtils::Hash
instances.
.PP
Like autobox, the effect is lexical in scope and can be disabled:
.PP
.Vb 2
\&  use List::Objects::WithUtils::Autobox;
\&  my $foo = [3,2,1]\->sort;
\&  
\&  no List::Objects::WithUtils::Autobox;
\&  [3,2,1]\->sort;  # dies
.Ve
.SS "\s-1CAVEATS\s0"
.IX Subsection "CAVEATS"
You can't call \fBnew\fR on autoboxed refs (but that would be a silly thing to do
anyway \*(-- and if you're really determined, \f(CW\*(C`[]\->copy\*(C'\fR has the same
effect).
.PP
It's worth noting that methods that create new lists will return blessed
objects, not native data types. This lets you continue passing result
collections around to other pieces of Perl that wouldn't otherwise know how to
call the autoboxed methods. (Some methods do return the object they were
originally operating on, in which case the original reference is indeed
returned, as expected.)
