This is the innovation in D(regarding this issue) - that on
struct types, the same operator is used for BOTH the value type

BETA is the successor to Simula and it does not distinguish
between value or reference and only use dot reference. What they
do instead of having a dereference operator is to have a
"reference operator" and also a "pattern operator" for type
variables. So it works something like this:
Call a and send the output as the input to b and then store the
result:
(1,(2,3)) -> a -> b -> (c,(d,e))
Assign reference a to b (instanced class/function)
a[] -> b[]
Replace class-type variable a with class-type b (not instanced,
which is equivalent to a class-type/function pointer)
a## -> b##
It makes a lot of sense for an OO language since we usually use
the referenced content more often than we want to change the
pointer.
