D interpreter?

[Brendan]

It would be a great boon if there were a D interpreter where you just 
write some code to try out. The most obvious advantage I see is that it 
would become a lot easier to learn D, especially if it's one's first 
language.

Another advantage I see is that it possibly attracts more people towards 
D, which could further D's advance to become a mainstream language 
(which is one of D's goals, I presume). This perhaps in turn would 
provide more books written on D by people who know much about it, which 
would possibly attract even MORE people to D. Well, you get the basic 
point which is cause and effect.

If I had the skill, I'd start up such a project myself, but alas. So, 
I'm just throwing in the suggestion (which I think was suggested at 
least once before).
