Re^2: Style and Preference on Loops

for my $idx ( 0..@$mysql ) {
[download]

Of course, that should read:

for my $idx ( 0..@$mysql-1 ) {
[download]

Though my version was not incorrect, I agree this is probably a better alternative here. Generally, I dislike the ungainly `$#some_array` syntax and it's rarely needed. For example: `$some_array[$#some_array]` [download] is better written as: `$some_array[-1]` [download] because, apart from the unpleasant-to-read `$#some_array`, the second form avoids the duplication of `some_array`.
