Interesting Error - Can't use string ("1909") as an ARRAY ref while "strict refs" in use

[Julian Field]

Okay, try changing the line to these two lines:

     my $line = int(scalar(@{$body})-1;
     while (${@{$body}}[$line] !~ /^\s*$/) {

This really is a bug in Perl. Every variable has a string value and a 
numeric value, depending on context. So $a[1909] should equal 
$a["1909"]. But in this case it's using the string value, which it can't 
use, and not the numeric value, which it can.
