Re: What would you do?

[merlyn]

# set even elements of @list to 'hi'...
$_ % 2 or $list[$_] = 'hi' for 0..$#list;

And yes, the comment would be mandatory.

I would like to underscore the wisdom of merlyn's comment comment.

Not only does his comment exist, but it is a succinct explaination of the code. (It is not an English translation of the statement like: do nothing if default variable is not mod 2 otherwise set the list of the default variable to 'hi' for the size of the list.).

Good example - good style. I wish more people would follow this example! :)

How is the comment mandatory? It works fine without it.

[merlyn]

Maintenance programmers don't work fine without it. And they're much more expensive to upgrade and replace.
