- What does the table above tell us? It tells me more about the writer
- than about the languages itself.
-
- I did some projects with ST and C++ and really the differences
- are not that big. But you have to realize that C++ is NOT and OOPL, it
- is a multi paradigm language, so comparing C++ with ST or any other
- OOPL is not quite fair.
-
- Many of the ratings in the table are simply not true. For example
- portability. When you use PARTS (from Digitalk) to build your GUI
- you're talking about code that can't be ported to any other
- smalltalk environment! Or when you're using the ODBC interface
- of Digitalk and you want to switch to VisualAge, you a have a major
- problem!
- And what about pure Object Oriented paradigms like data encapsulation?
- ST does not support that basic paradigm, so which of the compared
- languages is pure OO? May be Jave but not Smalltalk.
-
- For a fair comparison you have to use more items to compare. The
- few you used do not give the complete picture!
-
- I think that your comparison contains to much black and white,
- show me some gray and you will see that the differences are not
- that big.
