That's probably because you come from a C++ background.
I think that if you're used to Java, then you won't make this mistake.

Anyway, in D, objects (of classes) are always by reference, never by 
value!! never!

structs default to by-value, but if they are an inout parameter in a 
function, I believe they will be references.
