Effekt – A research language with effect handlers and lightweight polymorphism
How does this compare to other effect-oriented languages like Koka, Frank, and Eff?<p>I&#x27;ve been doing some work with Koka lately, but I briefly looked into the other three (including Effekt) and it mostly came down to, &#x27;Koka seems most active in development&#x27;[1] and &#x27;Koka had the easiest to use documentation for me&#x27;[2], which are both kind of subjective ways of choosing between them rather than an objective comparison.<p>[1] E.g. <a href="https:&#x2F;&#x2F;github.com&#x2F;effekt-lang&#x2F;effekt" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;effekt-lang&#x2F;effekt</a> had its last commit back in June; <a href="https:&#x2F;&#x2F;github.com&#x2F;frank-lang&#x2F;frank" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;frank-lang&#x2F;frank</a> last commit last year; but <a href="https:&#x2F;&#x2F;github.com&#x2F;koka-lang&#x2F;koka" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;koka-lang&#x2F;koka</a> last update was Oct 15. Effekt seems semi-active, at least, compared to Frank. While stability is good, I wouldn&#x27;t expect it in a language actively being used for research.<p>[2] Comparing <a href="https:&#x2F;&#x2F;koka-lang.github.io&#x2F;koka&#x2F;doc&#x2F;book.html" rel="nofollow">https:&#x2F;&#x2F;koka-lang.github.io&#x2F;koka&#x2F;doc&#x2F;book.html</a> and <a href="https:&#x2F;&#x2F;effekt-lang.org&#x2F;docs&#x2F;" rel="nofollow">https:&#x2F;&#x2F;effekt-lang.org&#x2F;docs&#x2F;</a> and <a href="https:&#x2F;&#x2F;www.eff-lang.org&#x2F;learn&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.eff-lang.org&#x2F;learn&#x2F;</a>
