Chained operator block syntax

[kazcw]

Spec: https://github.com/enso-org/design/blob/wip/wd/enso-spec/epics/enso-spec-1.0/03.%20Code%20format%20and%20layout.md#chained-operator-code-blocks

Example:

nums = 1..100
    . each random
    . sort
    . take 100

Should be equivalent to:
nums = (((1..100) . each random) . sort) . take 100

This is implemented in the parser but not yet supported in translation. I think it could be desugared to applications in the IR?
