I am trying to follow this as I use hashes all over the place. What exactly is a soft reference. Perldoc says this:
Symbolic references are names of variables or other objects, just as a symbolic link in a Unix filesystem contains merely the name of a file. The *glob notation is something of a symbolic reference. (Symbolic references are sometimes called "soft references", but please don't call them that; references are confusing enough without useless synonyms.)
I understand the difference between hard and soft links in a filesystem, but in Perl?
