Re: C++ in the kernel

Hi Poul,

Thanks for the feedback.

not be the correct augmentation for this purpose.

I should point out that I am not recommending the habitual use of C++ for FreeBSD kernel development, nor am I condoning that we accept C++ code into the tree without any *less* consideration than might be the case for contributions in other languages (usually C).

I reiterate: as per my message to Alfred, C++ makes it very easy to write bad code, but despite this, it is a very powerful tool when wielded properly.

My experiences in working with C++ have been very positive, although limited because I have been very choosy about the subset of the developers, and C++ code, that happen to exist in the world...

Instead of repeating myself, I'll just refer to my previous ramblings
on the subject and the SoC correspondence on the 'K' language
experiments.

I could not find any reference to this discussion in a mailing list search. I did read the article at: http://wiki.freebsd.org/K. It sounds like a new and interesting approach to a C-like language (* see footnote).

However, that was not the original topic of my thread, which is to gauge interest for C++ runtime support in FreeBSD and if anyone is already doing this.

C++ is happening *now*, in other environments, it is more relevant to what people are doing in the wider world than K, so I don't see how K is analagous to C++, it would be most helpful if your discussion on this issue were more easily available.

The ultimate litmus test is how it gets used and if it's a qualitative, and quantitative, improvement.

regards,
BMS

(*) It sounds like K reinvents Microsoft's Structured Exception Handling (SEH). GCC have had a Google SoC student working on porting SEH to GCC, I contacted their SoC mentor this week to try to find out what the status of that code is.
