got to know.. 'Leda'

I just came across a new programming language called Leda when I was reading the book 'Thinking in C++' by Bruce Eckel. What is so unique about Leda is, it is a multiparadigm programming language. Multiparadigm, I mean, has all the paradigms of programming languages implemented in it ie., imperative, object-oriented, functional and logic!

As we all know that these abtraction of programming languages were basically to address the problem needs to be solved by the computer. As in imperative languages the problem space and solution space were different, so it became tedious for a programmer to map the spaces with each other. And then came the better abstraction, object-oriented programming. Here the problem space and solution space looked similar! like.. all were treated as objects ie., the abstraction was catered in a way that it fits the real world. Later we had functional and logic paradigms which had their own conceptualization of the real world ie., as 'lists' in LISP and 'algorithms' in Prolog. So there came a point that every paradigm best suits only for the particular kind of problem that it was catered for.

So Leda was designed to have all the paradigms in one language and the programmer can chose the paradigm based on which will best suit his problem to be solved. It was founded by Timothy Budd. There is a book named 'Multiparadigm Programming in Leda' authored by the founder himself. I tried finding a free soft copy of this book to learn more but in vain. But I got a research paper on this topic from my univ's 'Adaptive Systems and Languages group'. Will post more when I get time to read that paper.
