I'm also not a fan of passing Optionals into methods. Most of the time it's easier and cleaner just to write an additional method without that optional parameter.

It can grow cartesian though.

I think the best compromise is to declare a new data type for the argument, such as:

  data ExecutionDirectory = ExecuteInCWD | ExecuteInDir FilePath

And take an ExecutionDirectory instead of a `Maybe FilePath`.

Of course, you need light-weight data declarations for that.
