Well, perhaps my terminology wasn't the best.
The basic idea is that when 'read' scans a string literal, it yields a constant
string rather than a mutable one. Similarly for when you load string literal
from an .elc file, or restore a string from a dump where the string came from a
string literal, etc. So evaluating a string literal gives you a constant because
string literals are self-quoting and they are constants already.
