No support for generics or custom allocators, combined with no desire to implement a package manager. The language author accepts that (1) Hare is just as limited as C and (2) C has no way of implementing a good hash map. > Recall that Hare is designed to be similar to C in terms of scope and goals. C also provides no general-purpose hash map, and little by way of other data structures (though some attempts exist, none of them good). So you're stuck using a crappy general-purpose hash map that you have to convince your linux distribution package managers to maintain.
