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.

Yeah it should be $" // "" or defined $" ? $" : "", but you wouldn't do that normally. :-)

But, your first suggestion made me shudder.

That was the point. :-) Seriously tho, that trick can be useful, interpolating constants (which really is calling subs) inside of a string, or more specifically a here doc can be nicer than precalculating and interpolating in.

It can be, but it does come with caveats. Aristotle and I had a short exchange about them once: Re^2: CGI and why?. Basically it boils down to "be wary of context."

I freely admit to using "@{[...]}" fairly regularly myself, though, so I don't mean to discourage it when it makes sense.
