My point was that EOF is relatively cheap compared to raising the exception
not that it is cheap per se. And if GNAT and ObjectAda (the 2 compilers I
have any source for) are typical of most implementations then this is
certainly
true. OA even includes lots of local instantiations of the sort that MAA was
finding very slow (assuming OA is also "slow" in this regard).
