It is a game chager for D, or a least huge step forward but what
is the killer feature against a betterC done through C++ + STL ?
Can anyone who really know both D and C++ godlike say why D as
betterC and not C++ as better C? Maybe Andrei or Walter ?
Learning a new language (as opposed to playing with it, which
takes hours) takes a lot if investment in time. So please somone
help us pople new to it.
1. D BetterC blogs says no RAII.
2. No high level library available. C++ has the whole power of
STL which can be used in a better C mode. D has to use only C
standard lib. STL gets you covered for a lot. This is *huge* win
for C++. I cannot overstate how important this is.
3. No exceptions. (Blessing or curse ?) C++ in a betterC mode
4. saftey. Full saftey is neither D as better C in C++. Arrays ?
use STL. Uninit locals varibales ? good compiler implementation
-Wall -Werror.
5. Most C++ features cannot be inhibited with a compiler switch.
Oh well. This sucks.
6. No array overflows in D. STL solves this. Design by contract
in D and not in C++. Usefull for some projects.
7. Modules. This is big for keeping things neat. Not in C++.
8. metaprogramming. better in D no question about it, even after
a couple of days one can see this. Static introspection. Not in
C++, but it will come. D wins for now.
9. Easy to port C to D. Should be as easier to port to C++ with
saftey features.
10. Ecosystem. C++... the whole computing world rests on a C/C++
titan. A lot of quality code which have run sometimes in exces of
40 years getting mentenance and bug fixes. What is D situation.
11. Sintax. D prolly wins here especially for metaprogramming.
12. Speed of compiles. D is fast to compile needs quantifying.
LDC/CLANG not dmd/clang comparisions. same lvel of optimizations.
Then you can get an accurate ideea. Speed of compilation is king
for bottom up design.
13. Refactors. C++ is meh. Tools arrise to make this easier. How
is D here ? Also
great feature for bottom up design.
14. Debugging. How are debugging tools in D compared to C++ ?
D as betterC really is a game changer, for anyone who cares to
give it a try.
Yes, it really is.
