Sorry for late reply.
R.uniq is a lazy function. It could be possible to omit (), but I am not sure if there is any need for it.
R.toPairs is not lazy (it's not possible to make it lazy). "data-first" and "data-last" use the same version.

omit ()

const obj = { foo: 'bar' };
const result = R.pipe(
  obj,
  R.toPairs
); // [ [ 'foo', 'bar' ] ]

@BetterCallSKY Hmm that sounds plausible :) But then please help me understand this example from the readme:

// Get first 3 unique values
const arr = [1, 2, 2, 3, 3, 4, 5, 6];

const result = R.pipe(
  arr,                    // only four iterations instead of eight (array.length)
  R.map(x => {
    console.log('iterate', x);
    return x;
  }),
  R.uniq(),
  R.take(3)
); // => [1, 2, 3]

Why is uniq used with parens here then?
