a sets implementation

[Stephan Diehl]

being new to D (I have a Python background), the first thing to try out 
was a set implementation. Since there seems to be quite an interest in 
this topic, I thought to share this implementation even though it's 
probably quite horrible for the seasoned D programmer :-)
The code can be found here:
http://codespeak.net/svn/user/stephan/d-hacks/sets.d
It tries to capture the look and feel of python sets.
Any comment/feedback is quite welcome.

Cheers

Stephan
