I'll admit to most of that.  But, I find that it is a common
thinkographical error for me to not realize that the second condition
will be evaluated even when irrelevant, and that it often works 
out that an exception is raised when the second condition is
evaluated.   That probably comes from too much time coding in other
languages in which the short-circuitedness is controlled by a compiler
option that is typically set to short-circuit.   IOW, when programming
unconsciously, I am more likely to write a correct program if I
habitually use the short-circuit forms than if I don't.   Following
this style will also serve as a form of negative encouragement for 
functions with side effects, which is also good.
