@$ is just another array. It has no special meaning. (Except that use strict dosen't complain about it even if you don't declare it, and it's always in package main)

    THX! So, what is $$ in this context, the PID?
[reply]
      It usually is the PID, yes. However, it's been assigned another value, so it's just a random global variable now.

        Indeed. I was told once not to play with those (maybe good advice in a non-obfuscational setting). I can see that in a strict setting they are part of main and therefore do not need a declaration. Crafty.

      Yeah! (Should be|It is) the PID. Nice, eh? :]
