In both cases you can just "return null;", which will work in most cases.

You can't do this in D either ('=' does not give a boolean result). Check your facts before posting ;)

Have you considered using:
	foreach(key;aa.keys.sort)
		writefln(key, " => ", aa[key]);

"null" works as a "literal" expression for arrays and AAs. That's why "cleaning" works - it simply sets the reference to null, and the GC will clean up the old contents sooner or later.


P.S. Your method of replying is very confusing, it's almost impossible to find the actual context of your messages. What newsreader software do you use?
