What's the value of code that's easy to read, but incorrect?

Low, possibly negative. But once you fix it, it is code that is both correct and easy to read, making it superior to the code that is correct and hard to read.

For this you first have to spot the error. Using one style you get help from the compiler, while with the other you need angry users and some debugger voodoo.

The compiler can be (fairly easily) modified to alert the user to the errors that the order of comparison operands people like me find natural makes possible. People-like-me's brains cannot be easily modified to find the order of comparison operands people-like-you find sufficiently cautious natural.
