Yes.  However, you typically also need some way to build structures
where not all components are literals.  If you have that, do you still
need the literal-only recognizer?  Of course, you might also consider
supporting, say, {a,{1,b},2}, where a and b are locals, and that would
be possible, too, but where do you stop?  I guess we will see a period
of overuse while people explore that feature (and, of course, other
people claiming that recognizers are devil's work), until we get a
good feel for where it is appropriate and where not.
