Because C++ exceptions are evil. They were a stupid design decision that 
wasn't thought out and not actually implemented until many years after their 
conception. 
They are as a result impossible to support for compilers without serious 
trade-offs in either space or speed. (either 20% slower or the need to 
included debug-info to unwind. Compiling with exceptions does the same as 
using -g1)

The short lesson in every C++ book except Stroustrups is: Don't use them!
