Not GP, and I'm just surfing unfamiliar docs, but it looks like, yes, there's general parameter polymorphism,[1] but also "modules" presented as structs,[2] and the polymorphism of struct constructors can have nontrivial impacts[3](eg Map(KeyType,void) loses value setters). Fwiw.

[1] https://ziglang.org/documentation/master/#comptime "Compile-time parameters is how Zig implements generics. It is compile-time duck typing." [2] https://ziglang.org/documentation/master/#import [3] https://ziglang.org/documentation/master/#void "By using void as the type of the value, the hash map entry type has no value field, and thus the hash map takes up less space. Further, all the code that deals with storing and loading the value is deleted, as seen above."

interesting, thanks
