Papers on Dynamic Languages

[Jay Parlar]

For one of my grad school classes, I'm writing a paper on "Dynamic 
Languages". What a wonderfully vague topic (but at least it'll let me 
write about Python).

Anyway, I want to talk about things like typing disciplines (weak, 
strong, etc.),"class vs. prototype, JIT technologies in dynamic 
languages, interactive interpreters, etc.

I've got Brett Cannon's thesis already, but I'm looking for references 
to some more papers on these topics. A Python basis for any of the 
papers would be preferred, but anything will do.

Any suggestions? This is my first real research paper in grad school, 
so I'm starting out from scratch here.
