[cfe-dev] Best practices

[Matthieu Monrocq]

I seriously doubt that synthetic benchmarks are very much valued. They are
nice to expose pathological behaviors, but not much beyond that.

It just seems that this is of lower priority than other stuff (C++11
support !!) and that you just happen to care more about that the average
user.

Still, this is an open source project, so if nobody deals with it and you
happen to really need it, maybe you could delve into it yourself or try to
find someone to do it for you ? (maybe even a contractor) The community is
generally welcoming to developers, so don't be shy :)
