As I'm now in the process of helping my 5-year old son learn to read, changing English is starting to seem a lot more attractive. Explaining why the same letter combinations are pronounced differently in different words makes him look at me with great suspicion. > Should we change the C++ Standard to allow 'void main(){' or teach > programmers to write correct code? Note that 'void main()' does not cause any actual problems. Either the compiler accepts it or it doesn't, but it doesn't make the code behave any differently one way or the other. > What should we do to fix problems with the inexact nature > of floating point arithmetic?

There is nothing that can be done technically to deal with it - arbitrary precision arithmetic is orders of magnitutde slower, for example. Order of evaluation difficulty, on the other hand, is a problem caused solely by the poor definition of programming languages. It can be fixed in compilers without affecting users or making them change the way they do things. It leaves correct programs correct, and additionally corrects programs with unspecified or undefined behavior. It's all good. --- [ comp.std.c++ is moderated.
