Re: [sv-ec] Version 9 of the proposal for mantis item 978 was uploaded

In yesterday's svec meeting we were looking for some new wording for the
unique and unique_index array locator methods. Below is what I have come up
with. Any feedback is appreciated.

From:

unique() returns all elements with unique values or whose expression is
evaluates to a unique value. The queue returned contains one and only one entry
for each of the values found in the array.  The ordering of the returned
elements is unrelated to the ordering of the original array.

unique_index() returns the indexes of all elements with unique values or whose
expression is evaluates to a unique value. The queue returned contains one and
only one entry for each of the values found in the array. The ordering of the
returned elements is unrelated to the ordering of the original array. The index
returned for duplicate valued entries may be the index for one of the
duplicates.


To:

unique() returns a queue that contains one and only one entry for each of the
distinct values found in the array. When a with expression is specified the
results of evaluating this expression are used to determine which entries of
the array are distinct. Elements of the original array are returned. The
ordering of the returned elements is unrelated to the ordering of the original
array.

unique_index() is the same as unique except that unique_index returns the
indexes of the array elements instead of the array elements themselves. The
index returned for duplicate valued entries shall be the index for any one of
the duplicates.
