[Qt5-feedback] new Qt5 - great! - but: What about exceptions?

[szyk100]

Hi all

One of modern languages feature included in C++ are exceptions. 
Exceptions have mainly one advantage and only one real disadvantage.

Advantage is: clear separation "fast path" and error handling - for me 
this is huge advantage and I realy like this feature. It is the same big 
leap in programming as invention "code modularization" concept. I 
suppose you think "who care about some excepitons", but we have only few 
modern concepts in C++ and rule "full backward compatibility" stops many 
great innovations (see: D or Python language features for comparision). 
Ignoring such great feature as C++ exceptions is ununderstandable 
self-limitation.

The only real disadvantage you (Trols) mentioned some where on your 
pages is that executables will grow 20% with exceptions enabled. But as 
you known during last 6 years drives and memory modules grown enormusly. 
And I suppose that situation is similiar like with OpenGL - this is very 
common and maybe limited devices will disappear quickly from the market.

Other your argument (but emotional in this case) was "historical 
reasons" for not using exceptions. If we will still thinking like that 
we could not using C++ for historical reasons (WinApi and Xapi or OpenGL 
api) and stay with raw C language. With argument like that we can even 
stay away from concrete and steel and using only stone and wood just 
"for historical reasons".


thanks for reading and considering
