digitalmars.D - So what about -betterC flag?

I remember that there was some buzz around undocumented -betterC 
compiler flag that should allow people get away from hard 
druntime dependencies and write bare metal code, drivers or 
kernel modules in some limited D subset. Could you make some 
comments about it. Does it exists and is it practical thing to 
do? What limitations does it require for your code? Is anyone 
using it right now and in what context? Thanks!

-betterC used to exist, not sure if it still does, but it does 
very little and I don't think it helps much; you're still 
basically on your own in making such code work right.

switch still there.  don't know what it does, if anything.

I see, it seems that all that flag does is prevent module info 
generation, I don't really know if it may be helpful or not in 
using D as a "better C" (without druntime). But thanks!

So... Has anything changed about the -betterC flag lately? It is 
now documented as a compiler flag, but there is no documentation 
on how to properly use it. Is it considered to be stable now or 
it is still a hack? What language features are forbidden when 
using this flag?

Not as far as I know. It remains useless.
