Of course there is the classic (from Ada): "Gee I need the cube of X":
	z := x ** 3;
which, of course (:-) generates the message "Ambiguous Expression".

The beginning student might be slightly confused by the reason:
   "The constant 3 is overloaded (as both integer and short integer)
    and there are 2 distinct ** operators, so the compiler doesn't
    know which to pick!"
If there are enough of these, the number of reserved words doesn't
matter as it plays no role in the confusion.

Note:  I'm not sure if there are enough in Ada or not, but reports
from people who have taught it as a first language suggests it works
reasonably well.  Besides there are weird things like this in all
languages.
