Indeed. I've checked the code and properties are explicitly not
allowed for
the C-style operators. The reason is that the x+=y is translated into
"x:=x+y" at the parser level rather than at the lexical level. This

that in case x is a property, at the point that this transformation
is
performed the compiler already resolved it into the setter property
(so it
can no longer access the getter).
Sorry if the following sounds stupid, but I'm a applications
developer, not a compiler developer. I do not know or understand the
internals of a compiler.
So is what you mentioned above by design, or an oversight?
I'm fairly certain that the C-style operators were implemented long
before most, if any, Delphi feature had been implemented (possibly
even before Delphi had properties).
We spoke earlier in another thread about hidden exceptions (rules)
which will just complicate things in the long run. Well to me, this
looks like one of those exceptions which the FPC core would like to
prevent.
Feel free to file a bug report.
Jonas
