I proposed a keyword, 'inject', a year ago.  Or it could be an
annotation.  I suppose such a keyword might significantly simplify
implmentation of external functions and properties:

@inject @property char[] chomped(char[] arr) {...}
@inject void sort!(alias pred, T)(T[] arr) {...}

Though prepending 'this' to the first parameter may also work, C# style.
