Hmm. I'll pass on that.

There are quite a lot of places in low level programming where you have 
to manage without them. Sometimes you have to do without the runtime as 
well. That doesn't mean you can't use C++ itself.

The vast majority of processors in desktop computers and above, sure. 
But do you think the one in my watch has one? My thermostat? The alarm 
clock? I've got at least a dozen devices with processors in this room 
with me right now.

There are an awful lot of these small things. Where power usage and cost 
matters far more than performance.
