Definitely.  Over time many of my non-FOR loops get switched from WHILEs
and REPEAT/UNTILs to LOOPs.  How many times have you seen this in code?

someVar := SomeFunction();
WHILE someVar <> someSpecialValue DO
  ...whatever...
  someVar := SomeFunction();
END (*While*);

With a LOOP this nicely becomes:

LOOP
  someVar := SomeFunction();
  IF someVar = someSpecialValue THEN
    EXIT (*Loop*);
  END (*If*);

  ...whatever...
END (*Loop*);
