Hi,

1. In Java an Object can be everything, even an array. Is there any equivalence
in D?

2. Java has a standard representation of the fundamental types as objects
(Integer, Float a.s.o.) I haven't seen that in D...

Without these functions it is a little tricky just to have a function f.ex.
like:

Object getProperty( String key );

..in D that can return anything.


Thank you for responding to our questions.

Answer: No you haven't, and you won't.  Java's type-wrappers are primarily
there for compile-time method-matching.  The primitive types are not
actually wrapped within the object model unless you explicity use it.

Answer: It can be done.  Templates, as one example.  And for that matter,
returning a single generic type has its possible problems as well, because
then you have to add checks (in some cases) to find out which type you've
gotten.
