I'm a bit lost. Are you saying that we should allow this:

shared int[] a, b;
...
a = b[2 .. 3];

on some machines but not others? How is then anyone expected to write 
reasonably portable code?

One great thing about Linux distros is that you are able to compile code 
on your machine. You get the source code, you run configure, you run 
make, you run make install, and you're good to go. How would it be to 
see messages like "On this machine this entire feature and consequently 
design doesn't work"?

I agree with disabling some feature on an odd machine, but not with 
conditioning entire areas of the language on the machine they work on. 
What is this, assembly language?
