'altering' the langauge is a pretty strong way to describe it.

I prefer to think of it as 'empowering the programmer'.

Now, choosing a keyword, will certainly be tricky, I accept that 
much. There is little consenus going to happen there, I guess.

As for your dscanner solution, that doesn't address the 
requirement.

And in any case, should D programmers have to rely on dscanner to 
pick up the problem with this?

     int var2 = 2;
     ip = &var2;
