No, it should mean if(arr.length). It means if(arr.ptr) now, and this
is incorrect. [..]
The meaning of if(x) for all x of nullable types has always been if(x !=
null) probably in all languages.
In fact, you can generalise further.
The meaning of if(x) is "compare the value of x with 0" (in C, C++, .. ).
The value of x for a pointer is the address to which it points.
The value of x for a class reference is the address of the class to which
it refers.
If D's arrays are reference types, then IMO they should exhibit the same
behaviour.
