Of course it was obvious; that was my point.

Walter had written that
   "if ("regex" ~~ "string")"
was functionally equivalent to
   "if (m; search("string", "regex"))"
and while that is true, it gives the impression that this was the *only*  
change to the new D. I just wanted to point out that the implicit  
importing of std.regexp was also removed.
