 // If the linear lookup turns out to be too expensive, the list
 // of closures could be maintained in a hash map, with the key
 // being the token position of the closure. There are almost no
 // collisions with this simple hash value. However, iterating over
 // all closure functions becomes more difficult, especially when
 // the list/map changes while iterating over it.
