I find that kind of answer disappointing. In this particular case, the
FreePascal developers could have just provided that guarantee.
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...
Is there at least a compilation warning if you access the variable after the
loop?
i would expect not unless maybe with the above mentioned languages modes and
mode switches... but they don't exist for this situation, AFAIK...
