1. Object Euphoria
Some info about Object Euphoria:
Object Euphoria is very full-featured and secure--it is also god-awful slow.
Some benchmarks:
Euphoria Object Euphoria
1,000,000 writes 0.01 s 37.80 s
1,000,000 reads 0.01 s 38.06 s
1,000 routine calls 3.08 s 3.13s
These are for Object Euprhoria v1.0 on Recent Contributions-- some simple
optimiztions have cut the read and write numbers to about 27 seconds. I
will agressively optimize the code and publish v1.1 with benchmarks ASAP.
OE will still be slow, and any full-featured OOP system will be.
If Rob implements namespaces and structures I can and will write a MUCH
faster OOP system.
I must mention Rod Jackon's excellent Quartz. Quartz does not provide
access control-- all data members are public and can be read/written to
directly without using the Quartz routines. (Rod's documentation warns not
to do this.) So I don't consider Quartz to be full-featured. But it is
fast: benchmarks are 1.54 s,1.05s, and 3.08s for writes, reads, and calls.

Object Euphoria is a comprehensive, Java-like Object Oriented =
Programming (OOP) system. Features include:
JAVA-style OOP with single inheritance and interfaces.
Run-time polymorphism.
Exception handling is provided for error recovery.
Normal, final (cannot be subclassed), and abstract (must be subclassed =
to be used) classes.
Normal, final (cannot be redefined by subclasses), and abstract (must be =
redefined by subclasses) methods.
Members, methods, constructors, and destructors may have public, =
protected, or private access.
Read access and write access for members may be specified separately.
Write access for members may be READ_ONLY, allowing a member to be =
initialized but not changed later.
Object and class members and methods.
Objects can only be accessed through the routines provided by Object =
Euphoria, direct access is impossible, providing excellent security.
Namespaces for classes to avoid name clashes in OOP code.
All this in a 45KB include file!
Let me know what you think about this.

Mike:
Indexed_sequence is type defined in both stdcont.ec and demo.ex
so when the stdcont.ec is included in demo.ex it causes an error

I inadventenly included an old version of stdcont.ec in objecteu.zip--the
new version works correctly.

For anybody out there still interested in OOP, I have just completed =
coding Object Euphoria, a very comprehensive Java-model OOP system for =
Euphoria. Features include:
1. Java-style classes with single inheritance and interfaces.
2. Exceptions for error handling--vast improvement over my previous =
submissions in this area.
3. Object and class members (data) and methods (routines).
4. Normal, abstract (must be subclassesed to create objects), and final =
(cannot be subclassed) classes.
5. Normal, abstract (must be overridden), and final (cannot be =
overidden) methods.
6. Public, protected, and private access for members and methods.
7. Separate read and write access for members.
8. Special read-only write access for members to define constants.
9. Optional constructors and destructors with access control.
10. All this in a 39K include file!
I am currently doing testing, coding standard classes, writing =
documentation, and working on demo ideas. I will upload to RDS when I =
have it finished. I eventually plan to write an Object Euphoria
wrapper for VEL, similar to David Cuny's Llama for Win32. I may also =
try a preprocessor version of Object Euphoria with dot notation,etc.
