The heterogeneous migration of computations allow computations to move between different platforms. It is a difficult procedure, that demands mechanisms for the capture and restoration of the state of the execution allowing for the identification of the structure of the computation and its data. This support, when offered, commonly appears in the form of ad-hoc solutions which are difficult to tailor or adapt to different needs. This thesis discusses the need for this support in current programming languages. This support must allow the implementation of different appliications that can profit from the ability of capturing and restoring computations heterogeneously, like migration and persistence. To experiment with this item, we extend the Lua programming language with an API that allows the programmer to reify the internal structures of execution into manipulable language entities, to explore the basic mechanisms a language should provide in order to support the implementation of diferent policies.
