An imaginary literal represents the imaginary part of a
<a href="#Constants">complex constant</a>.
It consists of an <a href="#Integer_literals">integer</a> or
<a href="#Floating-point_literals">floating-point</a> literal
followed by the lowercase letter <code>i</code>.
The value of an imaginary literal is the value of the respective
integer or floating-point literal multiplied by the imaginary unit <i>i</i>

  // cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
  // to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will
  // produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless
  // of whether the variable exists or not. Cannot be updated.

  optional. If the value is not provided i.e., the command looks like `wait --for=jsonpath='{expression}'`
  then the wait condition is interpreted as matched when the expression returns
  *any* single JSON value like object or a literal. ([#118160](https://github.com/kubernetes/kubernetes/pull/118160), [@minherz](https://github.com/minherz))
