in reply to eval point in hash ref

to eval commandline arguments is always prone to code injection

you might wanna use a simple recursion:

DB<119> sub dive { my $val=shift; $val = $val->{$_} for @_; return $val; } DB<120> $nethist => { "seek" => { messages => 42 } } DB<121> dive ($nethist) => { "seek" => { messages => 42 } } DB<122> dive ($nethist,"seek","messages") => 42 DB<123> dive ($nethist,"seek") => { messages => 42 }
