New bindings from the main clause and + last clause must override old bindings. This is done by some + additional set difference operations based on symbol identity. + Otherwise it is possible to end up with multiple bindings for the + same symbol, which is untidy. If the collect clause scrubs a variable + with forget and re-binds it, then combining that environment + with the previous bindings will create a duplicate. + Also, fixed a serious bug with the bindings from the last clause; + the append was wrongly put into the loop that processes the collected + lists. + +2011-10-04 Kaz Kylheku <kaz@kylheku.com> + * lib.c (acons): New function. (set_diff): Optimize common case: list1 and list2 are the same, or list2 is substructure of list1. |
