Is there any shortcut way to create an array and insert a single element 
(one line only)?

Instead of this:
    Object object;
    Object[] array;
    array ~= object;

I wanna write something like this:
    Object object;
    Object[] array = cast(Object[]) object;

Thanks

You can do something like this:

# array = (&object)[0..1];

It certainly will if 'object' is null at the time :-)

It can be null. The issue is if object goes out of scope when still using  
array. To be safe, use array = (&object)[0..1].dup;

I may be mistaken, but there appears to be no way to do this. :\ I've tried, and
pointer manipulations of any kind seem to be forbidden by the language.
(Ie. trying to set *(array[].ptr) = object causes runtime errors.) If this was
allowed though... I can think of several ways to do it.

The simplest solution would be array literals, which Walter has stated will come
into D in the future -- /hopefully/ before the 1.0 as I consider them an (nearly
anyhow) essential tool.  Once we have them, you would do something like this:

#
#  Object object = new Object;
#  Object[] array = [object];
#
