Put this category tag on pages describing known pitfalls and traps to avoid, especially in a programming language or library.
How is this distinguished from anti-patterns?
We also have a topic named LanguageGotchas.
And a category named CategoryDefensiveProgramming.
Where did that page go that mentioned "the last" programming bug ?
From memory, it was something like
if( enemy_missiles_detected = true ){
launch_missiles();
},
