I shudder at the thought of having to maintain code written by anyone who thinks
that this sort of construct is reasonable. Whether or not it's in the language.
Someone psychotic enough to consider writing this sort of thing is presumably
already having a field day with lambda. Heck, someone could do serious damage to
maintainability with nothing more than the basic operators and some precedence
rules...
