Superstition

"Always use strict," people say. "strict good!"
strict itself confers no benefits
The benefits come from avoidance of the bad practices forbidden by strict
- (Such as using global variables, or smoking in bed)
These bad practices are bad because they have certain negative effects on the program
Other practices may have the same negative effects
They are not forbidden by strict
Nevertheless, the problems are exactly the same
Conclusion: strict compliance is not enough
You must understand why strict is complaining
Otherwise you'll find other ways to achieve the same negative effects
