Even those may not be powerful enough. I have a use case where I was trying to read specification files to generate unicode tables. But using something like zig's @embedFile to get a handle to a []u8 in a comptime block doesn't work because I don't want the file to be embedded into the binary; I want something more akin to turing complete code generation. And I don't need it to run it on every compile, as the entire flow involves downloading said files off the internet, but only when a new version of the spec is released. I ended up just using code generation.
