1. Reworked patch from Andrey Oktyabrski (ano@spider.ru) with
functions: icount, sort, sort_asc, uniq, idx, subarray
operations: #, +, -, |, &
FUNCTIONS:
int icount(int[]) - the number of elements in intarray
int[] sort(int[], 'asc' | 'desc') - sort intarray
int[] sort(int[]) - sort in ascending order
int[] sort_asc(int[]),sort_desc(int[]) - shortcuts for sort
int[] uniq(int[]) - returns unique elements
int idx(int[], int item) - returns index of first intarray matching element
to item, or '0' if matching failed.
int[] subarray(int[],int START [, int LEN]) - returns part of intarray
starting from element number START (from 1)
and length LEN.
OPERATIONS:
int[] && int[] - overlap - returns TRUE if arrays has at least one common elements.
int[] @ int[] - contains - returns TRUE if left array contains right array
int[] ~ int[] - contained - returns TRUE if left array is contained in right array
# int[] - return the number of elements in array
int[] + int - push element to array ( add to end of array)
int[] + int[] - merge of arrays (right array added to the end of left one)
int[] - int - remove entries matched by right argument from array
int[] - int[] - remove left array from right
int[] | int - returns intarray - union of arguments
int[] | int[] - returns intarray as a union of two arrays
int[] & int[] - returns intersection of arrays

1. Reworked patch from Andrey Oktyabrski (ano@spider.ru) with
functions: icount, sort, sort_asc, uniq, idx, subarray
operations: #, +, -, |, &
FUNCTIONS:
int icount(int[]) - the number of elements in intarray
int[] sort(int[], 'asc' | 'desc') - sort intarray
int[] sort(int[]) - sort in ascending order
int[] sort_asc(int[]),sort_desc(int[]) - shortcuts for sort
int[] uniq(int[]) - returns unique elements
int idx(int[], int item) - returns index of first intarray matching element
to item, or '0' if matching failed.
int[] subarray(int[],int START [, int LEN]) - returns part of intarray
starting from element number START (from 1)
and length LEN.
OPERATIONS:
int[] && int[] - overlap - returns TRUE if arrays has at least one common elements.
int[] @ int[] - contains - returns TRUE if left array contains right array
int[] ~ int[] - contained - returns TRUE if left array is contained in right array
# int[] - return the number of elements in array
int[] + int - push element to array ( add to end of array)
int[] + int[] - merge of arrays (right array added to the end of left one)
int[] - int - remove entries matched by right argument from array
int[] - int[] - remove left array from right
int[] | int - returns intarray - union of arguments
int[] | int[] - returns intarray as a union of two arrays
int[] & int[] - returns intersection of arrays
