Is this possible somehow, or I will need to use foreach element of

The array doesn't have more levels, so I would like avoiding using
a CPAN
module that can copy an entire data structure.
The magic word is "cloning", called "deep cloning" sometimes when is
recursive as you want.
There are several solutions for cloning in Perl, for example the
dclone() subroutine in the standard module Storable.pm is one.
There's the Clone.pm module, and the modern Scalar::Util::Clone among
others.
