In C we have what we call dangling pointers where if a pointer is pointing to something else and if that something else is deallocated or removed from memory then the pointer that is pointing to that something else is now a dangling pointer. I've been learning the basics of perl but never get to touch pointers. Are there possibilities in PERL to have a dangling pointer? or can we even create pointers in PERL? i'm doing console apps and not for the web.
