Now we are just talking about using a sane naming convention for your types. Depending on the paradigm you are working in your instance of IBlaha has a consistent definition - in a trait or a class or whatever else you like. It also likely makes simple work for your IDE during refactoring as others have observed. You don’t get this from dynamic typing. Of course you could say the same thing about sane naming dynamic naming conventions for your declarations in a dynamically typed language - and you wouldn’t be wrong, but a compiler won’t help you in the case of human error. All I’m interested in is offloading as much complexity onto the tools at my disposal, so I can focus on what’s important. On my citation … that was tongue in cheek and I thought it was obvious. I don’t have a citation, this is all my own experience. For the third time, if you can work your way around this you have my respect.

Sure, the type IBlaha is defined somewhere just as the object(s) passed to add_item_to_cart are also defined somewhere. Again: "That it has type "Item" doesn't help you unless you have contextual information." It has nothing to do with naming conventions. Whatever simplistic tools does is irrelevant since this sub thread was about the meaning of two declarations in HN comment. Dynamically typed languages are very popular so it seems that many developers can work their way around dynamic typing.

  - Sure, the type IBlaha is defined somewhere just as the object(s) passed to add_item_to_cart are also defined somewhere. That definition is rarely as accessible as an explicit type though. For example take an API response or any third party library. Determining the data type isn't as quick as simply scanning a function for the object definition. - Dynamically typed languages are very popular so it seems that many developers can work their way around dynamic typing. As someone who has spent a fairly even mix of their career using typed/untyped languages, I think this is due to a few reasons: - Lower initial learning curve. - Lower barrier to entry. Those are real benefits, but I would argue most projects quickly hit a point where they benefit from static analysis. Having worked with 100s of devs at this point, I'm yet to meet one that after learning a typed language and using it for a sufficient period of time (more than a few months) wants to use an untyped language for anything outside of small scripts.
