In quest for more power, languages are often grown with new features. While it provides programmer with more freedom, does this actually achieve more power? Reg Braithwaite believes that this is not necessarily true and argues that it is possible to render language more powerful yet limiting options offered to programmers.
In his latest blog post, Michael Feathers argued that object oriented programming languages offer some built-in features that facilitate testing and are therefore more recovery friendly than functional languages. Proponents of functional languages expressed strong disagreement with this statement, which provoked a very passionate debate in the blog community.
Designing for flexibility and robustness: Asynchronous message model, OOP and Functional Programming
According to Pragmatic Programmers it is preferable in OOP to avoid design based on returning values. Michael Feathers argues that it may also be better to use the asynchronous message model that might be instrumental for improving adaptability and robustness. This maps well to the Erlang model though opposing some of the principles of pure functional programming.
Now that Ruby holds no secrets from him, Antonio Cangiano explains why and how Haskell will satisfy his passion for language learning.
