I've been trying to map out the rules that govern manipulation of $[. Basically what I want to do is something like: 
@rray = ( 'foo', 'bar', 'spam', 'eggs' );
for ($calar=0; $calar < @rray; $[++) {
   print "$rray[$calar]";
}

but when I run the above code I get That use of $[ is unsupported at obf.pl line 2. The below code sort of works, but the value of $[ gets reset to 0 for every iteration so I get a console full of foo. 
@rray = ( 'foo', 'bar', 'spam', 'eggs' );
for ($calar=0; $calar < @rray; $[ = $[+1) {
   print "$rray[$calar]";
}

Even if I increment another variable and assign its value to $[, I get the same That use of $[ is unsupported at obf.pl line 2. error as before. What is going on? How can I use $[ to freely play with arrays?
