in reply to What does the SHIFT bit do in a constructor

Leaving all this class constructor stuff alone :
if you use shift without an array as argument it will shift from @_ (which is the array of arguments passed to a sub) when called in a sub or from @ARGV (which is the array of arguments passed to the perl program) when called from the main program body.

Thus :

myshift("testme"); sub myshift{ print shift; #same result print shift @_; }
