No it should not. "use string" and 'use strict' are specially recognized
syntax. The *only* reason that they reuse the syntax of expression
statements, rather than being, for example,
use strict;
without the quotes, is so this pragma would be ignored on older pre-ES5
browsers without causing the programs to break. It is not in any meaningful
way string-like.
`use strict` should no more be recognized that should ("use " + "strict").
