e.g.

# map.py
def func(a: int) -> float:
    return float(a)

map(func, ['str'])

      raise ArgumentError(f"{d} is a directory")
   return d

parser = ArgumentParser()
parser.add_argument('output_file', type=file_path, help="Path to 

We get the return annotation for free, so we should allow users to do something with it.
