Quick question

I have a sub that takes in a ref to an array of arrays, and localizes. I later do something to a cell in the array of arrays to which that ref refers, and I get a "useless use of private variable in void context" error that I don't understand in this context.

sub mysub { $arrayref = shift; ... $arrayref->[$x][$y] = 1; }

Later:

Useless use of private variable in void context at mymodule.pm line 16 +6.
