Purpose: describe what Tcl considers a list element - i.e. the basic
component of a list.
----

Given that [Tcl] considers everything is a string, then a list element is, at its core,
just a string.  This string can either be 0 length, 1 or more characters, and can be formatted in such a way that the element is also another list.
