Hi, I tried using types on class constants which resulted in an error. I'm trying to enforce a type of a constant on a child class, which can currently be overwritten. I want to use top abstract classes, a sort of the main data processors and its children as configurations. Example: https://pastebin.com/sWuFTrFr I find it very clean to use constants for this purpose, but I haven't found a way to enforce their type, other than using abstract static methods and defining their types and implementations in children. Example: https://pastebin.com/edit/bGURTbak The behaviour I expected was that if a class constant's type is defined then it's children could not override the type of the constant i.e. redefine it but not change its type. Example: https://pastebin.com/2LrcKjDp Is there a way to achieve strict types on child constants other than using methods? Thank you! Jelly
