Agreed. Inc x means Increment x.
Disagreed. Inc x, Sqrt(-1) or whatever.

I find += (and all its friends) very useful. On a case by case basis!

An example. If we are doing a stepwise calculation involving references 
to some other objects then
	$iMystery = $iMystery + GetMagicNumber(CurrentIdx)
a lot easier to debug some months later than
	$iMystery += GetMagicNumber(CurrentIdx)

Alternatively, if it is a "simplistic" calculation, such as say
Function HowOldWillIBeIn(Me as cOld, WhichYear as integer) as Integer

	Return  Me.Age += WhichYear ' ymmv depending on your birthdate

End
