This sounds like a great feature for writing absolutely 
horrendous code.

Imagine: variables declared in the middle of function calls. 
Variables declared inside the initialization of other variables.

     struct Point
     {
         double x = (double y = 0);
     }

     void main()
     {
         import std.stdio;
         readf("%f, %f", (Point p).tupleof);
         writefln("p = (%f, %f)", p.x, p.y);
     }

Is this really what we want? If someone submitted code like this 
to one of your projects, would you accept it?
