+1. A friend of mine is "still experimenting" with 'with' and I hate reading his code. :)

with (new C()) {
    i = 42;    // is that a member of C?
    j = 43;    // how about that?
    foo();     // and that?
    bar();     // and that?
}

Thanks for obfuscating! :)

import std.stdio;

int foo()
{
   writeln("foo");
   return 0;
}

void main()
{
   short i;
   try  switch (i)
   {
      writeln(i);
      default:
         writeln("default 1");
         throw new Exception("");
   }
   catch(Exception e)  do switch(foo())
   {
      default:
         writeln("default 2");
   } while(false);
   finally if (i) switch(i) { writeln("do"); default: }
   else {}
}

One bug with this funny stuff sharing common scoped statement is

import std.stdio;

bool foo()
{
   writeln("foo");
   return true;
}

void main()
{
   short i;
   switch(i) if (foo())
   {
      default:
   }
   else
      foo();
}

It seems that if statement even doesn't reach backend.
