Yes. $: applies only to tacit programs or tacit components of sentences.
The simplest way to get a stack error is
$: 0
(but if you can make it crash in 9.4 or later, please report how you did
it and what your JVERSION is)
$: means 'execute the verb phrase I was contained in'. $: by itself
means 'execute myself' with nothing to stop the recursion.
$: is difficult to define in words.

3. In no case does $: refer to a larger unit than the sentence it appears
in, for example an explicit definition in which it appears.
