Hi,

My name is Leandro Damasio and I have started to follow Harbour Project Main 
Developer List few days ago. I recently started 2D Informatica with my 
associate Ted, to develop commercial aplications using [x]Harbour. We used 
xHarbour + BCC55 + HWGUI for about 3 years, until we read xhb-diff.txt document 
and decided to try Harbour instead.
We are about to realease 2DWGUI, an Object Oriented Harbour API to Win32 GUI, 
and its going to be a free product but not opensource from start.

Our experience with opensource development is minimal, but I believe we could 
be useful by giving sugestions and/or reporting problems at least.

My first try:

Does harbour have native support to singleton classes? Its an useful design 
pattern to declare unique instance objects, so the same instance is 
reacheable/accessible globally by just calling for the the class name.
We implemented Singleton objects in xHarbour, but I'm sure the native 
implementation should be done better by someone who knows the object machine 
inside.

The Singleton Class usage is like below:

<code>

CLASS Aplication SINGLETON

    DATA Status

    METHOD Init(aParams)
    METHOD Run()
    METHOD End()

ENDCLASS


Procedure Main (...)

Aplication():Init(hb_aParams())

Func2()

Aplication():End()

Return


Static Function Func2()

Aplication():Run()

Return Aplication():Status

</code>

If it is not implemented yet, do you think its a good idea to implement 
natively?

Thanks 
Leandro Damasio
