Hmm, and I reran it with literal params (I was using an @array) and I got that warnings as well. Interesting. OST. It follows from the fact @_ alises not copies, but still somehow surprising.
And it is also very interesting to learn that '00' evals to true. Definitely *not* what I expected. I was thinking that it would fall under the evals to 0 rule, but now I see not. Thanx.
On the other hand I tested a bunch of cases with 0's in them and I couldnt see how it affected the solution?
