Even though it isn't exactly the same as \@test, for your purposes it works the same.

It's doubtful that his real purposes are anything like the example he showed, so the differences between [ @test ] and \@test may actually be quite significant.

The first, [ @test ] actually creates a new array, a copy of @test, and returns a reference to it. The second, \@test returns a reference to @test itself.

If @test is big, making copies of it could hurt performance.

Also, because the data is copied, changing an element in the array referred to by [ @test ] won't have any affect on the contents of @test itself. Sometimes that's just what you want. Sometimes it isn't.
