Re: Short or Long Hand

Not so useful for a short list like this with only two elements, but

if(not @{[grep {$day == $_} (0,6)]}) {
    # foo
}

Not much of a gain here, but imagine if the list were 20-30 elements.

I think you're aiming for obfuscation there. The `grep` operator returns the number of matches in a scalar context, so you could have just said: `unless (grep $day == $_, 0, 6) { ... }` [download] -- Randal L.

I like that. Although it's a good argument for something like an `in` operator. `if ($day in (0,6))` is (to me) much cleaner in meaning, even if it's just syntactic sugar for the grep.	[reply] [d/l] [select]

I like that one, I have a use for that when I'm working out my month end dates which in my case are not always the last day of the month. Thanks	[reply]

If you are doing much date manipulation at all, you should strongly consider using one of the fine modules available: DateTime, Date::Calc, Date::Manip, etc. There isn't much learning curve; most have FAQs with cut-and-paste recipes for common tasks.	[reply]
