Tsk, tsk.

Your code had only the reference to join when you posted, and after Caron showed the @{[ sort @animals ]} idiom, then you added that as well.

Not good, Roger. At least, acknowledge that it was an update. Don't learn from somebody else's worst practices.

Damn, I thought nobody saw that. ;-)

You must have seen my initial post within the first minute I posted, 'cause I updated my post before davido made his first post.

I hesitated to include the interpolated hash slice solution initially because I think of it as an obfuscated over-kill, but included in my update for completeness. I was going to add the print "$_ " for @animals solution too but stopped short because that solution will print an additional blank space after the last element in the array, which I consider as not a proper solution.

So the answer is -
yes, I admit I have updated without labelling it as an update.
no, I didn't see Caron's post before my update.
