not really... backwards compatibility and all that... borland's TP and BP do the 
same... at least back as far as v6... i can't get to my v5 or v3 to test but i 
daresay that they, too, do the same... looking forward from them, i would hazard 
a guess that delphi also does the same...

but then again, perhaps the devs could provide that guarantee in one of the 
available language modes... perhaps with an additional mode switch...

i would expect not unless maybe with the above mentioned languages modes and 
mode switches... but they don't exist for this situation, AFAIK...
