A more realistic example is $ for hex numbers. A sensible implementation
is to define that in the minimum search order, such that words added to
Forth itself can start with $ e.g. $= to compare two strings.

This shows me how to Lift this defect. Rename LITERAL to (LIT) and
define
: LITERAL 'LIT , , ;  IMMEDIATE
Then the above test succeeds.
The interpretation syntax of LITERAL is undefined.
LIT, is a sneaky way to have an interpretation syntax.
Normal is
   : foo [ 1 ] LITERAL ;

In the standard:
LITERAL :
Interpretation: Interpretation syntax for this word is undefined.

What if the standard says
   execution of this word while in interpret mode is an ambiguous condition

then I would gladly throw an exception if anybody tries it and the examples
wouldn't fly.

In view of the above, not yet.
