It seems to me that all this discussion about new operators such as ^^ is all caused by an oversight in the implementation of (actually lack of) booleans in C. If C had a strict rule that 0 is false, 1 is true and well, anything else, you take your chances, there would not be any need for any new operators like ^^. If the only legal value of TRUE is 1, ^^ evaluates the same as ^ in all cases, so ^^ would be unnecessary. Also, the only difference between && and & would be whether the second operation would always be evaluated or not. If the definition of ! were the same (!0==1, !anythingelse==0) then the old definition of non-zero =true could still be used by using !!x (or x!=0) which gives TRUE (or 1) if x!=0 and FALSE (0) if x==0. Also a one-bit new type (boolean or logical) could be created that used only 1 bit to determine TRUE or FALSE, allowing the use of huge arrays of booleans using little memory.

Also let's not forget that we need the assignment form of ====
which is

Now, has anyone got six of them?
