in reply to Playing with $[

The 'use' that perl is complaining about is '$[ = $[+1'. From perlvar,

As of release 5 of Perl, assignment to $[ is treated as a compiler directive

You can assign to it at compile time (ie $[ = 5; ), but cannot modify it at runtime (ie $[++; ).

    Okay, I get it now. So I could still do some playing around with 
    @rray = ( 'foo', 'bar', 'spam', 'eggs' );
$[=3;
$calar = $[;
print $rray[$calar] while $calar++<@rray;

    but not 
    @rray = ( 'foo', 'bar', 'spam', 'eggs' );
$[=$#rray
$calar = $[;
print $rray[$calar] while $calar++<@rray;

    Good to know. Thanks, jsprat
