I think types will be cheap. Doing magic might be something like:

  add fetch magic to value:
    new_type = copy_type(value->type)
    new_type->fetch = my_magical_fetch
    value->type = new_type

Of course, one of the standard types could be a "magic" type that checks
for per-value magic methods before dispatching to the value's normal type
table. I don't see that being necessary, but it's nice to know it's
possible.
