Re^2: order of arguments evaluated

That could be better written as

print join ',', @boxes;

unless you're concerned about the joined string being enormous, in which case I'd probably say

my $printed = 0;
foreach my $box ( @boxes ) {
    print ',' if $printed++;
    print $box;
}

But your code is perfectly safe. The alternatives are only evaluated if the corresponding condition indicates that they should be.

Indeed both are good suggestions, but the context was putting together HTML tables, hence a simple join wasn't satisfactory. The second solution was also good, but I was concerned about integer wrap-around, which could potentially evaluate to zero in the case of a HUGE table (being the paranoid programmer that I am, even though the likelihood of generating a 4,294,967,296 row table was unlikely). Hence the dodgy trinary operator statement.	[reply]

My second solution, like yours, will only increment the variable if it is zero, because logical-or is a short-circuiting operation. Before you get done generating a multi-billion-row table, I think you're going to have problems with browser timeout. `:-)` Caution: Contents may have been coded under pressure.	[reply]
