| Dec 5, 2016 at 17:34 | comment | added | Basilevs | Yes, that's good. A bit like vector, though :( | |
| Dec 5, 2016 at 17:32 | comment | added | Basilevs | I think, this means any non-monadic types are very underrepresented in FP and are non-trivial to deal with. Hence my request for non-monadic example. | |
| Dec 5, 2016 at 17:28 | comment | added | Doc Brown | @Basilevs: here is one: docs.oracle.com/javase/tutorial/essential/concurrency/…. And it means we have to work on our Google foo. I am also pretty sure if one makes himself through SICP, the question clarifies itself, but I did not want to reference a full book in my answer ;-) | |
| Dec 5, 2016 at 17:28 | comment | added | Basilevs | I was sure too and have not found one. Do you know what this may mean? | |
| Dec 5, 2016 at 17:26 | comment | added | Doc Brown | @Basilevs: this is always straightforward - instead of mutating an object for a certain operation, let the operation internally make a shallow copy of the object, replace the attributes in that copy by the modified values, and return the new object. Unmodified collections will be just copied "by reference", and collections which need to be "modified" will be replaced by the new collection returned by the immutable equivalent operation. I am sure there are beginners examples for this approach all over the web in different programming languages, can't just find a good representative one. | |
| Dec 5, 2016 at 16:58 | comment | added | Basilevs | I only see collections there, no complex non-uniform objects. Please clarify. | |
| Dec 5, 2016 at 16:55 | comment | added | Doc Brown | @Basilevs: I did not want to dive too deep into implementation details, the Wikipedia article I linked to leads to lots of good resources and examples | |
