It doesn't look right, even for custom types; because D (and in 
particular Walter) is against changing the meaning of operators 
when overloading (e.g. << in C++). At least unofficially, 
although I may recall it is enforced at a few places elsewhere.

Going back to the original question, it may be a bug (for 
arrays). And if so and if D wants to enforce consistent operator 
semantics when possible, it may be considered a bug for any type.
