However, instead of passing strings from one command to the next, marcel passes Python values: builtin types such as lists, tuples, strings, and numbers; but also objects representing files and processes. The bit before the semicolon sounds like what you'd do in a functional language like Elixir. It would be cool to be able to do this in regular Python programs. I know some libraries (like pandas) fake it by having a method return an object of the same class, allowing method chaining, but that doesn't work universally.
