Was hoping the author found a solution to (in my view) Zig's biggest shortcoming with generic types: a parameter that accepts all instances of a generic type must either (a) be declared as "anytype" or (b) also require a comptime parameter for the generic type argument. For example, the standard library passes around instances of std.io.Writer as anytype, so zls auto-completion doesn't work.
