Yes. You can use my serialization library [1]. Sergey is incorrect in
that it is not possible to serialize upvalues. You just can't
(de)serialize *shared* upvalues *correctly*.  My library uses an old
shareupvalue patch [2] I shared a while ago which the Lua authors now
have implemented in the form of debug.upvalueid and debug.upvaluejoin
in Lua 5.2.

In any case, you can still serialize most functions with upvalues correctly.
