I have an ill-defined project, whose precise definition will need help from powerful concepts provided by strange and/or powerful programming languages such as Haskell, LISP/Scheme, O’Caml, or Prolog.
To be fluent with such a language, I need to invest some time learning and mastering it. Only then will I be able to determine whether it is really useful for my project.
So my Wish of the Day for today is for a selection guide, which lists a series of questions about the project and then makes a reasoned recommendation for one of the powerful languages for that project. For example, if one of those languages is indeed beautifully abstract but is poor in having runtime libraries and does not provide for linking to alien libraries (imported from mundane languages such as C, Perl or Python), then the language is ruled out for a project, which needs extensive support for manipulating XML files, playing with sockets and doing direct file I/O.
