I like this.  I'd like it better if it integrated with the adapter  
PEP, so that the freezing mechanism for a given type could be  
pluggable, and could be provided even if the original object did not  
contemplate it.  I don't know where the adapter PEP stands: skimming  
through the (most recent?) thread in January didn't give me a clear  
idea.

As another poster mentioned, in-place freezing is also of interest to  
me (and why I read the PEP Initially), but as also as mentioned  
that's probably unrelated to your PEP.
