Which is actually property-like because assigning to length
does pretty complex stuff. So the member cannot be named as
'length':
struct Array (T)
{
size_t length_;
T* ptr;
}
Anyway... :)

To be pedantic dynamic arrays are implemented in D simply as
struct Array
{
size_t length;
void* ptr;
}
and there is no type parametrization since such arrays handling
is opaque for users (in druntime they are treated as void[]).
Parametrization can be useful in user side since performing any
operations with structure above (void*) will lead to errors. But
in user side there is no point in manipulating the structure
directly, as it can be done using usual properties/druntime
without template bloat. By the way, the style ABI page is
written, allows implementation to have more fields.
