- If you don't use strict, we won't want to help you.
- If you still don't use strict, we will NOT help you.
- It will catch mispelled variable names.
- It will catch missing '$', '@', '%', and '&'.
- It will force you to actually know what variables you're using.
- It will not let you use local unless you specifically say you want to. (Instead, you have to use our to scope globals.)
- It will prevent variable-clobbering due to scope changes. (You still shouldn't use the same variable name in different scopes, but this helps even if you're silly.)
- It will help you program better.
- It elevates Perl from the level of shell-scripting to the level of a true application.
- It makes maintenance of Perl applications possible. (I'm not exaggerating about this one.)
- And, the most important reason is "Because I said so."
We are the carpenters and bricklayers of the Information Age.
Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
