Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Optimizes AST by moving nested nodes from the array level to one level deeper:

Examples:

Removes unnecessary iterations by items of the same array.

prefix "foo", nested: true
list do
  # ...
end

# Becomes:
list do
  prefix "foo", nested: true
  # ...
end

Removes “flat” operation that cannot be applied to non-hashes

prefix "foo", nested: false
list do
  # ...
end

# Becomes:
list do
  # ...
end
