Is this an example from some well-known compiled language? I work mostly in C++, and this is a feature I've wished for for a long time.

Swift and C# appear to have this feature, though they use the syntax fetch(accountId, history: true, details: false);

Kotlin does this https://kotlinlang.org/docs/functions.html#named-arguments https://kotlinlang.org/docs/functions.html#named-arguments

  Nope! > "When you use named arguments in a function call, you can freely change the order that they are listed in." That violates a key requirement in my specification, which means that I regard it as broken. Positional parameters should take arguments only in their designated argument position. Only non-positional parameters (keyword parameters) should be allowed to be specified in any order.

    Is there an example you have in mind as to why the params, if passed via keyword, would need to stay in their position? It sounds like external calls made to the internal api without the headers being present? Trying to understand why the position/order would matter to you once arguments are named?

If the code base supports designated initializers I'll use them as a way of getting named parameters like so: struct SomeArgs { bool normalize{false}; int stride{2}; char ch{'x'}; ... some other stuff }; void someFn(SomeArgs args); someFn({ .stride = 1, .ch = 'y' }); someFn({ .normalize = true }); not as simple as python but it's close-ish and more readable than: someFn(false, 2, 'c');
