Sorry, FINAL solution.

Please have a look at the second: print $hash{code},"\n";
It prints a CODE(0x..)-Ref, but is not executable. Any Hints, Thanks, Carl 

#! /usr/bin/perl
# Write-Read-Execute code
#

    my %hash = ();
    $hash{code} = sub { print "Hi Guy - Hello Fellow!\n" };
    &{$hash{code}}();
    print $hash{code},"\n";

    my $string = str_Code($hash{code});
    $hash{code} = code_String( split(/\n/, $string) );

    # this should work (as before saved):
    print $hash{code},"\n";
    &{$hash{code}}();

# the two subs
sub str_Code {
    use B::Deparse;
    return B::Deparse->new("-p", "-sC")->coderef2text( shift )."\n";
}

sub code_String {
    my $ret;
    while ( @_ )
    {
        $ret .= (shift)."\n"; # "\n" was eliminated by split
    }
    # NOW MAKE $ret been executed:
    # This is the examlpe of B:Deparse:
    #eval "sub func $ret"; # but nothing happens

    # this causes this mistake:
    # Undefined subroutine &sub
    #&{$ret};

    # this should be given back:
    return \&{$ret};
}
