in thread Finding Redundant values in arrays

This won't work. The for (@test) line iterates through each element of @test, but then you skip each element with the grep you're using. In English you're saying: for each element in the array, only keep that element if it is not in the array.

Also, there is no need to place quotes round $_.

Update: This is wrong. dvergin explains what really happens in Re: (zdog) Re: Finding Redundant values in arrays.
