One should not obstruct access to such a vital tool. It is perhaps the most powerful glue functional programmers possess. This paper provides further evidence that lazy evaluation is too important to be relegated to second-class citizenship. Assuming this isn’t just a lack of knowledge or resources on my part…does one new (since the advent of Haskell) non-strict language count as success for “the Haskell project” ? If that’s the view of the majority of the Haskell community, then these remarks of mine are redundant, therefore I can delete them. Let’s see: have any new non-strict languages made their way into widespread use…so far, the only one I’ve been able to find is R. The next Haskell will be strict, but still pure.Ĭan the Haskell community now relax, confident that programmers everywhere have a reasonable understanding of “non-strict, purely functional programming languages” ? The next ML will be pure, with effects only via monads.Purity is more important than, and quite independent of, laziness.
…so has this changed - has Haskell been so successful that we can now start up new site-specific languages like Mu and Verse? With the notable exception of Miranda (see Section 3.8), all of these were essentially single-site languages, and each individually lacked critical mass in terms of language-design effort, implementations, and users. Languages that contributed to this lazy Tower of Babel include: There was a strong consensus at this meeting that more widespread use of this class of functional languages was being hampered by the lack of a common language. In September of 1987 a meeting was held at the conference on Functional Programming Languages and Computer Architecture in Portland, Oregon, to discuss an unfortunate situation in the functional programming community: there had come into being more than a dozen non-strict, purely functional programming languages, all similar in expressive power and semantic underpinnings.
#Epic meaning in cs verification#
PS: In fact Epic is looking for more people who know about programming language implementation (implementing Verse), and/or formal verification (reasoning about Verse). I think this is extremely generous, and it means that I will continue to be pretty active in these areas. And probably more.Įpic is also happy for me to spend a substantial amount of time on education, on functional programming research, and Haskell and GHC in particular. I also expect to work with Dan Piponi on data-centre-scale transactional memory. listen to Tim Sweeney’s SigGraph 2019 talk). Verse is a new programming language that Epic is designing for their games, and in due course for the metaverse (e.g. I will be working with my long-time colleague Lennart Augustsson and a team of others, on Verse. Time for something new! I am going to start a new role as Engineering Fellow at Epic Games in December.Įpic is doing all sorts of interesting things – not just games but other virtual reality stuff suchf as special effects for films, design visualisation, architecture, and so on. As you may know, I am leaving Microsoft Research at the end of November.
