When D is not nice

[Frank Benoit]

String concatenation in Java:

"abc " + a + " bla";

where a is an interface ref.

Ported to D, this look like this:

"abc " ~ (cast(Object)a).toString ~ " bla";

This are 3 steps more:
1.) explicit cast to Object (interface/class compatibility!)
2.) explicit call to toString
3.) put additional parentheses

I would be happy if we could remove all three of this annoying points.
