C is 50 years old or something like that, and it still doesn't have a standard hash map.

Sure its not impossible for C to get that, but at the same time, they are trying to write git not fix C.

* My point is, that hash maps and data structures like that are clearly not the priority of C or they would **exist by now.

** by exist I mean either in C standard, or a at least a community consensus about which one you pick, unless you need something specific.
