works! You don't need to type (*p).member. Isn't Go awesome!

Stole from D? You mean java right?
There is no value type objects in Java so no. More likely C#.
Nope - C# uses -> to access member of a struct referenced by a
pointer. See
https://msdn.microsoft.com/en-us/library/50sbeks5.aspx
The difference between reference types and pointers is that with
reference types, THERE ARE NO value varaiables. So it's safe to
use . instead of -> for accessing member through a reference
because there is no value type, because there is no such a thing
as accessing a member of a reference type without dereferencing
it. So it's safe to do so on classes in C#, but not on structs.
This is the innovation in D(regarding this issue) - that on
struct types, the same operator is used for BOTH the value type
and the pointer to it.
