IANAImplementor, but I suspect that virtually all of the performance hit could be incurred at run-time, if it happened to be implemented that way. The memory hit too, if necessary, but that would then make the performance hit hit very hard indeed. I suspect that it would be better to preserve the Poddish parts of the AST structure and just have them transmogrify into the appropriate Pod objects on demand. Damian
