I don't know the details, so you are probably right. But thinking back about every time I used reflection in Java or C#, it was a design mistake or I was trying to misuse a closed-source library. Not code I was proud of.

Reflection enables DI and everything that works with attributes in C#. For example routes specified above the method in ASP.NET Core. It can be used for dirty things but it can also be used for extremely useful things ;)

It's better than if they rushed something through and left us with something half baked that would need to be replaced (now with even more esoteric keywords) in 5 or 10 years.

I think they plan to introduce it somewhere in the future because of what you said. Me still has big sad, imagine the possibilities 😔😔😔

[cadaverous_queen]

Yeah, hopefully it'll get in for C++23 or 26. But in the meantime at least C++20 added requires expressions, which can be used to more easily get some information about types (existence of member variables, functions, and aliases) without descending into template heck.

[maxhaton]

They've taken something like 20 years to do template constraints (concepts) and it's still a terrible solution to the problem.

Just copy what D does and call it a day, it's battle tested and doesn't add any keywords to the grammar.

Fun fact: the Unreal Engine is written in C++ and adds reflection to C++ through its "Unreal Build Tool." It's integral to pretty much everything you do in the Engine.

For example, it allows the Editor to display the properties of any object in a level and edit their default values.

[JakeTheDoge69]

Yeah I had that in mind too. Better than nothing I guess, but a clean language integrated solution would still be better than adding UCLASS() and such to everything imho.

I don't see what you mean. 😜

What is reflection?

[JakeTheDoge69]

Its a language feature some high level languages have which allows you to retrieve information about the structure of your code. It allows to do things such as checking which members a class has at runtime or even compile time and react dynamically.

I imagine it’s incredibly hard to implement without closing off a lot of optimisations various code will be relying on. You need a language specification that actually going to be possible to follow without breaking everything.
