I never said they wouldn't create bugs, but not fully understanding a line of code (outside of needing to conceptualize external dependencies) is certainly frightening after 20 years of working in C.
What it shows is that sort of code never shows up in practical C. There's stuff in Java (and Javascript for that matter) I don't understand, and I've been programming in those for about as long as anybody.
If Jon Bentley can have a bug in his Programming Pearl book then so can anyone.
