Yes this. I always see people raving about the mathematical beauty of three-value Boolean algebra, but any programming language where testing if foo = foo can return something mechanically equivalent to false is just plain broken.
Yes, I get that it's pure and mathematically beautiful, but over here in the real world I've squished an endless supply of bugs caused by this absurdity, and in languages where there is no null-aware equality test, the composing the proper check is absurdly verbose.
