Re: Re: Re: Re: Re: Small question: Why can't I print "@-"?

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.

(I do agree that avoiding $"\|\|"" is better; it's ugly and prevents joining with "0".) 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. --- demerphq _{First they ignore you, then they laugh at you, then they fight you, then you win. -- Gandhi}	[reply] [d/l]

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. -sauoq "My two cents aren't worth a dime.";	[reply]
