NAME
       Set::newHashSet - Create a new empty HashSet.


SYNOPSIS
       HashSet<a> newHashSet( Int buckets=157, Int(a) hashfn=hash )


ARGUMENTS
       buckets  The  number  of  hashing  buckets  to use. A larger number of buckets increases the speed of the
       dictionary (up to a limit) but  uses  more  memory.  A  good  choice  is  the  nearest  prime  number  to
       1.5*(expected number of entries) , with the default being 157.

       hashfn  The hashing function to use. This function must take a key, and return an integer. A good hashing
       function will return different values for similar keys (but must of course always return the  same  value
       for  the  same  key!).  A  default  built-in hashing function is provided, though if the keys are of type
       String , the Builtins.strHash (3kaya) function should be used instead, and if the keys are  of  type  Int
       you  may  use  Builtins.identity  (3kaya) (though an array may provide faster insertion and lookup if the
       keys are positive and either small or largely sequential). If the keys are  an  especially  complex  data
       type,  it may again be best to write your own hashing function. This argument may be omitted and defaults
       to Builtins.hash (3kaya)


DESCRIPTION
       Create a new empty HashSet.
