If we're going to do this operator, I would prefer a regular arrow:

    import { sortBy, filter, map } from 'array-like';

    let names = document.querySelectorAll('.entry')
      -> sortBy('title')
      -> filter(entry => entry.getAttribute('data-url') in whitelist)
      -> map(entry => entry.getAttribute('name');

I personally find this more readable than either the bind proposal (which looks too much like a property access, and not enough like a function call, to me) and the proposed pipeline operator, which doesn't have an immediate meaning to my eyes.
