[fpc-devel] C style operator doesn't work with properties in 2.3.1

[Boian Mitov]

This is if you like the risk of using "with" ;-)
This works until somebody changes the FDayList[WeekDayNum].Rows[Timeslot] to 
contain CountSlots property, and all your code is broken ;-) .
If you want stable code, never use the "with" or else ... ;-)

  With best regards,

Even shorter:

with itm, FDayList[WeekDayNum].Rows[Timeslot] do
    AvailableSlots:=AvailableSlots+CountSlots;

But nested or combined with-statements can be dangerous in case there
are multiple fields with the same name in the different records/
classes/objects.
