<div><tt>scanPairs(x,f)</tt> -- applies the function <tt>f</tt> to each pair <tt>(k,v)</tt> where <tt>k</tt> is a key in the hash table <tt>x</tt> and <tt>v</tt> is the corresponding value <tt>x#k</tt>.<p/>
This function requires an immutable hash table. To scan the pairs in a mutable hash table, use <tt>scan(pairs x, f)</tt>.<p/>
