Aaah. That makes sense. And works.

*But*: I copied my code from Phobos :D If you search for "in", with the 
quotes, in std/container.d, you'll find two occurrences. The actual 
live use (in RedBlackTree) is opBinaryRight (which makes sense), but in 
the dummy class, TotalContainer, which is described as "an 
unimplemented container that illustrates a host of primitives that a 
container may define", uses just opBinary. The doc-comment says that 
"$(D k in container) returns true if the given key is in the container".

So ... a "bug", I guess? (One that isn't really executed -- but 
still...) Worth reporting?

Anwyay: Thanks for the clarification :)
