	But only when FO joins this plattform too, enought momentum will be
generated (hopefully) to 
	motivate developers to switch from java to dylan, which is not easy
because of the many add-on libraries
	shipped with the jdk's nowadays (distribution, internationalization,
benas etc. etc.). Are there any
	plans to build a j-ffi for Dylan to use those resources?

	[marc]    
	Interesting, yes, but no big deal. Any set of macros written for
some specific
	domain create a domain-specific-language-extension to dylan. Depends
upon
	how much you (as domain-programmer) look behind and outside of this
set
	of macros.

	[marc]  
	Take a look at http://www.aspectj.org for some very good slides
	documentation and examples (java though:-(

	[marc]  
	Yes, like in CLOS. Dylan has no MOP so this might become difficult
to
	realize. 

	As an example for AOP (and before and after methods) suppose you
want 
	to temporarily add tracing to a set of methods. 

	define protocol <<some-protocol>> (<<protocol>>)
	    setters, getters, functions etc...
	end protocol <<some-protocol>>;

	define aspect <<some-tracing>> (<<aspect>>)
	    slot log :: <stream>;
	    before-all-methods-in  <<some-protocol>> do
	        format(log, "entering %=\n", get-current-method-name());
	    end;
	    after-all-methods-in <<some-protocol>> do
	        format(log, "leaving %=", get-current-method-name());
	    end;
	end aspect <<some-tracing>>;

	[marc]  Any ideas?
