Re: Sentances from arrays

Here's what I use:

sub list_commify {
    if (@_ > 2) {
        join ", ", @_[0..$#_-1], " and $_[-1]"
    } 
    elsif (@_ > 1) {
        "$_[0] and $_[1]"
    } 
    elsif (@_ > 0) {
        $_[0]
    } 
    else {
        ""
    }
}

Personally, I don't like if's. In my mind, they make code harder to read by forcing you to think your way through them. While they are appropriate in other cases, in this case I believe merlyn is clearer. =IndyZ	[reply]

To each his own, natch. For me, at least, it's easier to parse the if's, since it's more English-like. I can parse it by reading it aloud. I find it harder to pronounce the `? :` version, though I appreciate its elegance.	[reply] [d/l]
