Did you notice that the example does *not* provide a solution? For good 
reason, IMO, because the changed property handling results in an code 
bloat for no specific reason. When the compiler could determine in the 
past, where assignemts to e.g. fields of record properties are possible, 
and where they are not, it can continue to do so.

My preferred workaround for the changed Inc/Dec behaviour is a macro, 
that allows to preserve exactly the old behaviour, without bloating the 
code. I wonder where there remains anything good, when the compiler then 
will have to process a macro and to do CSE, where it has not been 
required in the past, and possibly will generate *more* code for exactly 
the same result :-(

I'd wait at least for an official FPC release before changing the LCL 
code. Perhaps there will come a compatibility option, that allows to use 
the old behaviour even in new FPC versions.

Who defines the OPL? If compatibility with other than Delphi compilers 
is desired, according modes can be added.

The behavior/implementation of Inc/Dec is questionable, together with 
the stricter property abstraction. (see my above workaround)

Oops :-(
