can one use 'new'?
Yes. It can be used with any value type to allocate a block of
memory on the GC heap and return a pointer to that memory:
struct Foo { ... }
Foo* f = new Foo;
int* i = new int;
If yes, when should one use 'new'?
Whenever you need to allocate something from the GC heap. In my
experience, it's rare to need it with value types in D. I tend to
use it primarily with classes and arrays.
