Good idea, although I'm afraid of potential problems with interface.
Similar solution, with similar potential issues, is to create automatically
`input_file` when `input` is multiple or when specified in code. Moving
things to parser is definitively more advantageous for things like
overwrite but it may cause some code and reading duplication for Python
scripts.
