Blindly replacing "a += b" with "a := a + b" may lead to a semantic change
if "a" is an expression with side-effects.
Nevertheless, I do think that implementing += for properties is a good idea,
but unfortunately FPC developers disagree.
I do see that also properties could show site effects when used in a +=
expression, as they are accessed twice. But is this (in nearly all
cases) not exactly what the user would expect ?
