Light warning:

Deparse is mostly correct, like in this case.

I'd say in well over 99% of the cases.

But it's using heuristics for back- engineering the source from the op tree and I've seen cases where it was wrong.

One of the reasons is that optimizing the OP tree implies information loss. *

But there is also a list of perl idiosyncracies which make that harder to accomplish.

So please take the results with a grain of salt.
