I know that using "=" for assignment goes all the way back to Fortran and
Basic, but it has always been a source of confusion. That's why I would
prefer ":=" for assignment, and "+:=" for the increment operator.
The best symbol for assignment that I have seen is a left arrow, e.g. "count
? count + 1". Visually, it is quite suggestive of assigment (the value on
the right goes into the variable on the left) and it would never be confused
with testing for equality. Both APL and early versions of Smalltalk used the
left arrow for assignment. As far as I can tell, the only reason why the
left arrow is not used more often is that it is not a standard 7-bit ASCII
character.
