This SRFI specifies the procedure make-table, a hash table constructor compatible with SRFI 69 (Basic hash tables). The procedure make-table allows various parameters of the hash table to be specified with optional named parameters when it is constructed. These parameters are: the initial size, the minimum and maximum load factor, the key equivalence function, the key hashing function, whether the references to the keys are weak, and similarly for the values. By using optional named parameters, as specified in SRFI 89 (Optional positional and named parameters), the constructor's API can be easily extended in a backward compatible way by other SRFIs and Scheme implementations.
