//------------------------------Dict----------------------------------------- // The dictionary is kept has a hash table. The hash table is a even power // of two, for nice modulo operations. Each bucket in the hash table points // to a linear list of key-value pairs; each key & value is just a (void *). // The list starts with a count. A hash lookup finds the list head, then a // simple linear scan finds the key. If the table gets too full, it's // doubled in size; the total amount of EXTRA times all hash functions are // computed for the doubling is no more than the current size - thus the // doubling in size costs no more than a constant factor in speed.
