Sure, you could use one of those. But, why would you?

Would it improve efficiency? Uh uh. Clarity? Certainly not.

I can't think of a good reason... can you?

BTW, I didn't realize this was a "bug" fixed in 5.8. I was thinking that perl didn't like to interpolate any variables that didn't start with a \w character. But, putting the name in braces will work with other (admittedly poor choices for) variable names such as @% and @!, not just ones perl knows.

Actually I'd rate the second one ( without the $" || "" ) as the preferred way to go. I don't tend to like interpolating arrays in anything other than quick and dirty code. If I'm going to output a list I prefer a more distinct end of field character than a space.

But I _did_ put a smiley face on my node dude... :-)

Oh, I did see the smiley; it's just in my nature to take such suggestions seriously, I guess. Particularly when they come from you, demerphq.

Although I'm not prejudiced against array interpolation in strings, I'm perfectly happy with using join() instead. (I do agree that avoiding $"||"" is better; it's ugly and prevents joining with "0".)

But, your first suggestion made me shudder.
