Hey, why not have _local_ variable-tables ? That would be a real cool feature, especially as it would eliminate symbol-table pollution by temporary names when instantiating the same abstraction many many times, especially dynamically. Each patcher would have some kind of variable-table which would be destroyed as the same time as the patcher, just like an object's state is destroyed at the same time as the object, and just like a C function's state is destroyed when that function returns.
