Hi!

   This are limitations of Ada:

   1) Not 100 % OO, see Smalltalk

Not a limitation. Ada allows you to write code at a lower level than 
Smalltalk. I see this as a feature, Ada 95 is a multiparadigm language.

   2) Without distributed objects, see Modula-3

A distributed object system could be written in Ada. See also the Distributed 
Systems Annex of Ada 95.

   3) Lack of MACROS, see C++

I'm sympathetic, since I know real (Lisp, not C++) macros are powerful, but 
I found reading Common Lisp macro code pretty painful. Maybe the pain subsides 
after a lot of reading, but I understand the argument in favor of readability 
here. Besides, you can always write a macro language for Ada if you really 
want. There is just no "standard" one.

   4) Small number of operators to overload, see  C++

Agreed. But where do you stop? Do you allow user defined operators? I suppose 
I would like to be able to create user defined arrays that behaved just like 
built-ins.

   5) Lack of multiple inheritance, see C++

Show me a problem which requires MI and can't be solved fairly easily in 
Ada 95. There are quite a few online papers describing what you can do.

   6) Big language, see BASIC

Is that a limitation?
