As others already pointed out that most likely your $some_var[$i] is an array reference.

However, just for completeness, I want to point out that it could also be a symblic reference. If use strict is truned off for refs, that would be also correct from a syntax point of view.

However I am not a supporter of the symbolic ref usage.
It is worth to mention to new perl users, that $# can be used as lvalue.

This is extreamly useful, when you want perl to garbage collect your big arrays.

Just do
```
@a = (1..1000);
print "original array:\n";
print join(",", @a), "\n";
$#a = -1;
print "after set to -1:\n";
print join(",", @a), "\n";#You can not say for sure that your array ha
+s already been garbage collected at this point, but at least it is no
+w a candidator.
