According to the docs, | is syntactic sugar for the .pipe method.

  pipeline = task(get_data, branch=True).pipe(
      task(step1, workers=20)).pipe(
      task(step2, workers=20)).pipe(
      task(step3, workers=20, multiprocess=True))

That's probably the chained method approach for those with this preference.

Yeah, this seems neatest if you don't like line breaks

pipeline = (

    task(get_data, branch=True)

    | task(step1, workers=20)

    | task(step2, workers=20)

    | task(step3, workers=20, multiprocess=True)

)

Square brackets would create a list and braces would create a set of course. The contents still can be split over different lines-- just pointing that this syntax doesn't do the same thing.

The example at https://pyper-dev.github.io/pyper/docs/Examples/ChessDataAna... does exactly that.

Yeah I should have noted that they behave the same in terms of cleaning up a line, not necessarily in terms of what the compiler will do with each token pair.
