There are perhaps three things to be aware of if you're considering 
using Pyd:

1) Linux support is still missing. I get the impression a new GDC 
release is close, and it is my hope that this will change at that time. 
It's worth pointing out that CeleriD (Pyd's build system) already works 
in Linux for building extensions written to the raw Python/C API.

2) At the moment, Pyd is written from the standpoint of writing 
extensions to Python in D, rather than embedding Python in D. This is 
not to say Pyd wouldn't be helpful if you wanted to embed Python in your 
D code (at the very least, Pyd has the most up-to-date bindings for the 
Python/C API), but your code will essentially just be using the raw C 
API for many things.

3) I'm still cramming features into Pyd at a decent clip. I don't expect 
the existing API to change much, but be aware that new features are 
being added about as fast as I can think of and implement them.
