Hi all,

I would like to know what the recommended (and possible) methods are for
structuring a D application.

By this I mean: what are the techniques/paradigms available in the language?

For instance, I consider Lisp to have the following:

structured programming
object-oriened programming
functional programming
aspect-oriented programming (via auxiliary methods)
domain specific language development (via macros)

Thanks for any advice.

The quick-and-dirty rundown is that it follows very closely to C++:

Structured programming
Object-oriented programming
Functional (free-function) programming
Template (meta) programming

D doesn't foist any particular paradigm on the programmer.  They're all available so you can use the tool that fits best.

D also brings to the table some things that are not explicitly enshrined in other languages (at least, not all at once):

Template mixins
RAII-style objects ('auto' keyword)
Contract-oriented programming ('in', 'out', 'body' and 'invariant')
Unitesting ('unittest' keyword)
Built-in Delegate and Function pointer types ('delegate' and 'function').
Partial-array types

The last one is a real nifty feature: any array type can be extended one method-at-time via free functions, where the first argument is the type to be extended:

char[][] stringList;
char[] getFirst(char[][] list){ return list[0]; }

stringList.getFirst(); // first argument is substituted with 'stringList'

This is similar to a partial-class in C#, but only applies to array types.

Also on the menu are the fact that D is directly compiled to native machinecode (no VM), and sports a non-ref-counting GC.
