Possibly, we don't know yet - it depends on how successful we are.

Let A="Hello world!" : REM Type inference!
For I in A:
   Print I
Result: each character of the string on its own line...
Actually, I can do this:

10 FOR EACH a$ in ["Hello world!"]: PRINT a$: NEXT a$

10 DIM a(32)
20 FOR EACH b IN a()
30 PRINT b
40 NEXT b
or even

10 INPUT a$
20 IF a$ IN ["Yes", "yes", "YES"] THEN PRINT "Yay!" ELSE PRINT "Boo!"
and of course

10 IF b IN [1 TO 10,20,30 TO 40] THEN ...
20 IF c$ IN ["0" TO "9", "A" TO "F"] THEN ...
Where the first tests that b is between 1 and 10 inclusive, or is 20, or is between 30 and 40 inclusive. The second tests for hexchars.

Yes, it's not part of the original Dartmouth spec (and in fact is very close to Pascal) but then the original Sinclair BASIC did things that aren't in the spec - though their string handling was genius and stands up well even today - so what's wrong with making my interpreter do things a little better?
