( #3333=superdoc: print w/ replies, xml ) Need Help??

In a recent post I described a method I discovered for packing hashes and arrays. As part of the description, I typed a few examples into my REPL and pasted the output in the post; 10 lines of sample code being worth a 1000 words of verbiage.

But I just realised that I made a typo. Instead of using a template of n/(n/a*)*, I accidentally omitted the final *. But the mystery is, it still worked:

$packed = pack 'n/(n/a*)', 1..10;; @array = unpack 'n/(n/a*)', $packed;; print @array;; 1 2 3 4 5 6 7 8 9 10

The question is why? Why did pack see fit to pack all 10 values rather than just the first?

Is there a logical explanation, or are the last 3 digits of the id of the above linked node somehow responsible :)

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
