I like consistancy, and prefer:
my $col = 0;
$worksheet1->write(0, $col++, $_)
foreach @list;
Of course, you could use:
my $col = 0;
$worksheet1->write(0, $col, $_), $col++
for @list;
or even:
$worksheet1->write(0, $col, $list[$col])
for 0..$#list;
Personally, I think whenever appropriate
use the alternative forms here. This is
especially true of exceptional conditions,
e.g:
die "nicely"
unless foo == bar;
rather than:
unless (foo == bar) {
die "nicely";
}
which hides the purpose. There is room
in this world for preferences, just don't
expect mine to be same as yours :)
