ANN: Ctalk 0.0.55 2015-05-27 Released

Ctalk release 0.0.55 2015-05-26 adds overloaded math operators for
String, Collection, and Key objects, and members of their subclasses.
The overloaded operators provide a compact way to manage object
references. Among other uses, the references can act as ad-hoc
iterators, as in programs like this one.


    List new aList;
    Key new aKey;


    aList push "item1";
    aList push "item2";
    aList push "item3";


    aKey = *aList;


    do {
        printf ("%s\n", *aKey);
    } while (++aKey);


Note that *aList refers to the first member of the list, which is a
collection key, while *aKey refers to the key's content, which is a
String object. So an expression like **aList returns the first String
in aList.

Also new in this release are many methods, like String : chomp and
Object : isSubclassOf, as well as the methods that overload math
operators, including +, -, ++, --, +=, -=, !, and *. Methods in the
Collection hierarchy are now more consistent, and a few duplicate
methods were removed.


There's also an upgraded version of the, "methods," utility, and the
chaser.c example program, which displays a side scrolling message in a
terminal window.
