The only thing comes to mind would be complex expressions containing inline
specializations of generics. Due to the Delphi modes not using the
"generic" and "specialize" keywords there is some disambigity that the
compiler is not yet able to handle (most of these cases can however be
worked around either by explicitly declaring the specializations as types
or breaking the expressions up into simpler ones).
