(stricter than D.) They are currently duplicating the immutables.

I haven't finished reading.

Yeah, why not D?

Because Rust has typestates :-) It's an interesting language feature.

Another feature that may be important to them is the ability to manually 
arrange the data/program (don't recall which exactly) in memory.  I know 
one of the things they were experimenting with to speed up the browser 
was changing how the loader loaded the various libraries.  Perhaps this 
is taking it a step further to ensure their products load as fast as 
possible.

I have read about not-C languages designed for embedded CPUs that have
syntax&semantic to do this accurately. When your ROM/EEPROM/flash/etc is quite
limited, you want to use all its bytes accurately.

You can control the layout of your program in D on Windows with Optlink. It can 
make a big difference in load speed.

Hey that's good to know. Can you give us some tips or a pointer on
optimizing the app layout, or maybe some optlink tricks? Perhaps I
should read a book on that. :p

I do think D is still pretty damn fast in loading already. At least
from my limited experience with writing a basic GUI app using DFL..

Ed Borasky recently commented here at ReadWriteHack: "We flat out don't  
need any more programming languages! What we need is *efficient*  
implementations of the ones we have now and IDEs / version control systems  
that enforce software engineering discipline."

Now that is funny and most people seem to agree with him.

Can't this be done with GDC using linker scripts?
