The solution to your problem is to write \$self->${path}{qw($_)}, however, please consider the following:

  1. Don't use my $_ - either do for (...) {...} or for my $foo (...) {...} (lexical $_ is experimental)
  2. Always use warnings; use strict; (that'll give you the warning about my $_ as of Perl 5.18)
  3. Try very hard to avoid stringy eval - the current problems you are having with it are just the tip of the iceberg!

Instead of the string form of eval, in your case you can use closures:

sub mk_data_accessors3 {
    my $path = shift;
    for my $name (@_) {
        my $accessor = sub {
            carp "Warning: '$name' takes at most 2 arguments...\n" if 
+@_ > 2;
            my $self = shift;
            $self->{$path}{$name} = shift if @_;
            return $self->{$path}{$name};
        };
        # keep the scope of "no strict" as small as possible
        no strict 'refs';  # needed for *$name
        *$name = $accessor;  # install the sub
    }
}

mk_data_accessors3('data','bar');

print bar({data=>{bar=>456}}), "\n";  # 456

That keeps the depth of $path limited to one level of the hash, but I'll leave the rest as an "exercise for the reader" :-)
