Re: Forgot variable syntax for $var = funct() or "Funct failed\n";

or is one of the lowest precedence operators, even below =. This means that your code is parsed as: (my $hostname = call()) or "Can't resolve thing"; You should use || instead, or // if your value can be defined but false.

my $hostname = call() || "Can't resolve";
my $hostname = call(); $hostname //= "Can't resolve"; # Alternative so

Yes of course, it was implied in my first proposition. My point was that splitting a complex statement in two was also a valid way to disambiguate and obtain the expected value. I just used \|\| in one case and // in the second for diversity.	[reply]

... implied in my first proposition. Yeah, on second look, I have to agree that the point I was trying to make was quite adequately made in your reply above. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]
