Very honestly, shortly after your remark I've tried to use D in 
connection with cocos2d-x for a small mobile sports game, and 
after two days I've given up.

I've never managed to find an easy way to make D play well with 
cocos2d-x. Don't ask me about having it run on android.

But I'm not disgusted.

I still remain VERY interested in being able to developing all my 
desktop/mobile gaming developements in D.

It's just that it seems that I'm not smart enough to make this 
D/cocos2d-x/android magic happen by myself.

And as I said, I'd prefer to be able to regularly ask D to 
progressively collect its bits of memory in some limited and 
predefined amount of time (xxx ms) when and where I've decided 
to, in the Nim way.

For that also I'm clearly not smart enough to do the job by 
myself, and Dmitry has already explained me twice why he's 
against that...

So at the moment I'm just waiting that some D/GC/Android genius 
manages to make the impossible possible...
