Re: [ANN] com.walmartlabs/cond-let 1.0.0

Yes, I wouldn't have bothered if I had known about better-cond, so there you go. I think I first wrote this code at Aviso at least five years ago. On Wed, Oct 3, 2018 at 7:22 PM Mark Engelberg wrote: > This looks like a case of "convergent evolution". > > Having the ability to do a :let in the

Re: [ANN] com.walmartlabs/cond-let 1.0.0

The short-circuiting is a 'feature' of letting the type control the sequencing of operations. In practice you mix multiple interacting monads depending on what your requirements are, for example I regularly work with Deferred Options and Deferred Results. In clojure, you could try to add a

See https://funcool.github.io/cats/latest/#mlet for something closer to home, in the monadic vein. On Thu, Oct 4, 2018 at 4:10 PM Gary Trakhman wrote: > These are all just sugar over monadic bind, right? > > Here's one way to do it in the ocaml alternate universe: >

Re: [ANN] com.walmartlabs/cond-let 1.0.0

These are all just sugar over monadic bind, right? Here's one way to do it in the ocaml alternate universe: https://github.com/janestreet/ppx_let#syntactic-forms-and-actual-rewriting But it can be made to work for async or options or whatever, too. We can put the async helpers in the same

[ANN] Polylith: A software architecture based on Lego-like blocks

Polylith is an architecture that has been inspired by the simplicity and composability of functions. We asked ourselves the question "what would a system look like if we could build it with high-level blocks that share the properties of functions?". It turned out that the answer looks a lot
