in reply to Why you should use strict

After you've gotten fairly comfortable with perl, I strongly recommend you always load the strict module in all your programs.

Why wait until one has become fairly comfortable with potentially bad habbits? When developing in Perl, always:

use strict; use warnings;

There is no reason not to. Using strict and warnings will speed up your learning and your development process. Failing to use them will inhibit you considerably.

One might argue that there are situations where strict and warnings might prevent someone from intentionally, and with full understanding of the ramifications, doing something that strict and warnings see as suspect. I submit that in those rare instances, strict and warnings may be temporarily disabled, or directed to accept a particular thingy. But don't throw out the baby with the bathwater. Just disable them in the portions of code that you know and understand why a stricture violation is still ok. I venture to assert that such cases will be few and far between in normal development.

It is a "Good Idea" to reinforce among both novices and experts alike, the use of strict and warnings. Experts will already know its value. Beginners and novices might not. They should be encouraged to use those pragma's from their very first "Hello world!\n";.

[Corion]: Yay. Traditional finance situation averted. Bonds can be quoted in amounts (1_000_000 EUR) or per unit (1 unit). And a traditional error is to trade 2_000_000 piece when you meant to trade 2_000_000 EUR.
[Corion]: (one of my scripts simply catches high amounts and I phone people making that trade, ideally before the payment is due)
[Corion]: The sad thing is that my script sits at the end of the pipeline and can only look at the payments due today or tomorrow basically, while there are many more systems further up in the pipeline
[GotToBTru]: better late than never, I guess
[Corion]: GotToBTru: Sure - there is a long and sad story of many frantic cleanups that led us to implement this notification ;)
