dependencies:

stack run on a new example project with these dependencies gives:

For more context: I'm attempting to use amuletml as a dependency because I want to parse a type definition file that looks like

type Module <- { name : string, on_load : () -> () }

and generate a C++ header that looks like

#pragma once

struct Module {
    std::string name;
    sol::protected_function on_load;
}

// ... etc methods for checking/getting/pushing Module on/from/to the Lua stack, also autogenerated

and I am guessing that using Haskell with Amulet as a dependency is the easiest way to accomplish this.

Hrrm, not sure what the correct behaviour here is. I guess we catch the error and use some "?" version instead.

Ahh, dammit. It hadn't occurred to me that addDependentFile would need it to have the file exist.
