Why the following code fails to compile?

Technically you can modify the members of the temp record (just to
have the work thrown away afterwards).
So I guess the compiler forbids it, because the only case it would
ever be done is: by mistake.
Btw, this works (or actually not, it works wrong)
with MyObj.RecInstance do {begin} ii := 123; {end;}
Now you could do some work with the temp result, and have it trashed at
the end of the "with" block.
However, fpc incorrectly changes the value in the original record.
Yet, don't use it. It will (likely) change, and stop working. (or work
correctly, changing the temp value only).
