Yes, I did some experiments with c++ as well, but here are the drawbacks.
1. ABI instability. It's very hard to maintain ABI compatibility with C++.
2. Slow startup time and large symbol table due to unnecessary export of
many long symbols caused by name mangling.
3. Significantly larger binary size + dependency on libstdc++.
4. UTF-8 support is not widely available. STL strings works with ASCII
only. wstrings need additional encoding conversion.
5. No reference counting support. Using boost::intrusive_ptr may solve
this, but the code will become very long.
6. Compilation is really slow for large projects.
7. Harder to debug.
8. Hard to use in non-C++ projects, such as some plain C programs and vala
projects.
9. Too complicated and hard to master. Error-prone if not used correctly
10.Existing code is almost finished. Rewriting with C++ is just a waste of
time.
11.Vala provides similar code readability but 100% integration with GObject
without additional dependency. I think it's enough for me.
12.I fully agreed that the objects provided by C++ is cleaner than the
terrible GObject runtime system. However, the additional costs and side
effects it brings just offset the benefit. Porting to actually C++ means a
complete rewrite.
Personally I like C++ and use it under Windows since it's very difficult to
develop Windows programs with plain C.
In this case, I think C language is a more suitable choice, especially when
it's intended to be used in other C programs.
