How is it ambiguous? Dependent type systems/algorithms can be weaker than desired, but there's no way you can say Zig has dependent types.
- stateoff 8y agoI think Andy refers to this [1]. For example you can do: const std = @import("std"); fn Int(comptime value: i32) type { return struct { pub fn value() i32 { return value; } }; } pub fn main() anyerror!void { const int3 = Int(3); const int4 = Int(4); std.debug.warn("Types: {} {}\n", @typeName(int3), @typeName(int4)); std.debug.warn("Sum: {}\n", int3.value() + int4.value()); } Output being: Types: Int(3) Int(4) Sum: 7 Edit: The compiler does the right thing: [2] https://godbolt.org/z/eLWeU2 https://godbolt.org/z/eLWeU2 [1] https://ziglang.org/documentation/master/#Generic-Data-Structures https://ziglang.org/documentation/master/#Generic-Data-Struc...
