When you pickle a function, you get a reference to the function, not the actual function code. Right - that's usually what I want. (I've used pickle to store tests against game assets, e.g. that a model has all of its textures checked into perforce, or that a texture for a model does not exceed 128x128, unless otherwise specified). Marshalling functions is usually a non-starter for this, since a) it's complicated to analyse the call graph before execution, and b) native functions can't be marshalled - an awful lot of code executed against this asset pipeline is thin bindings over native/Java/C# code. Maybe I have found the 1% of the Python use-cases where lambdas suck a bit and everywhere else it's fine--it would be great if my experience was exceptional and no-one else had ever had a similar problem doing something else.
