This implementation (some really nice code by Niels Grewe, removing  
something that had been on my TODO list for a couple of years) is part  
of the EtoileFoundation framework.  This has no dependencies other  
than an OpenStep implementation and has been tested on both GNUstep  
and OS X.  I think there's an XCode project for OS X (I've never used  
it, but I think Quentin's tested it on OS X and fixed some issues  
there) and a GNUmakefile.

It is closely tied to the ETCollection protocol, which is added via a  
category to all of the standard OpenStep collection classes giving a  
consistent interface (which is used by CoreObject and EtoileUI).

EtoileFoundation doesn't depend on any other parts of Étoilé, although  
most other things in Étoilé depend on it, and is BSD licensed.  You  
will need to compile it with clang to get the methods which take  
blocks as arguments (unfortunately, buy 4701 means clang doesn't work  
with the GNU libobjc headers at the moment; hopefully this will be  
fixed in the next week or so).
