Pattern: Nested percent literal
Issue: -
Within percent literals, nested percent literals do not function and may be unwanted in the result.
# bad
# The percent literal for nested_attributes is parsed as four tokens,
# yielding the array [:name, :content, :"%i[incorrectly", :"nested]"].
attributes = {
valid_attributes: %i[name content],
nested_attributes: %i[name content %i[incorrectly nested]]
}
