I'm resurrecting this thread because I'm actually hitting this problem myself! (To clarify: I have no problem handling the source code myself... I just need somewhere to put it.) Unfortunately, I don't think I can use this workaround, because I need to serialize *anonymous* functions — there's no var to which I can attach metadata, and I don't know of a way to create a non-global var to stuff into my data structures. I'm leery of interning tons of global vars, because this application will be up and running for months at a time. At this point I can see three workarounds for my case: * Define a structure of some kind that is essentially a metadata wrapper around a function, or * Maintain some external map from function object to its original source code, or * Drop down to Java and implement a class that's just like Fn (probably wrapping one) but also implements IMeta. I don't really like any of those. Any further thoughts from anyone? Is there any particular reason why Fn doesn't implement IMeta?
