Overview

Formats an array that contains only a list of variable references. To make things simpler, if there are a bunch, we format them all using the “fill” algorithm as opposed to breaking them into a ton of lines. For example,

[foo, bar, baz]

instead of becoming:

[
  foo,
  bar,
  baz
]

would instead become:

[
  foo, bar,
  baz
]

provided the line length was hit between ‘bar` and `baz`.
