I don't know any better, gentler way of saying this, but the code you posted above is very broken. As written, it won't even compile. Your first four lines are all assignment statements, and not a one has a ";" character to end the statement. Furthermore, I see nowhere where you are actually assigning any data to @trans or @superchunk. When you do:

@trans[1] = @superchunk;

You aren't assigning the "chunk" to the slot in @trans, the context there (caused by the left-hand-side being an array slice... did you mean that element, instead?) means that the first element of @superchunk will go into the second element of @trans, and since the slice needs no more data, no more copying will get done. Did you mean to assign the whole list contained in @superchunk, instead?

It is very difficult to glean much more from the code, I am afraid. I apologize that I couldn't be more positive.
