File_Exists doesn't exist?

File_Exists doesn't exist?

[David Weller]

Nothing like adding in functionality that isn't standard....one of our
junior engineers asked how to check for the existence of a file
without creating a block and catching a Name_Error exception after
calling open.  I looked at him like he was from outer space and told
him that was what the File_Exists operation was for.  Unfortunately,
there was no such critter (but an example in 11.4.2 shows such a call
(I know, just because it's there doesn't mean it's part of the
language, it could be used as an example)).

I know I can look to using Forest or some other similar library, but
can somebody clue me in to the history of this, I thought we had that
added for Ada 95.

I use POSIX_FILES.IS_FILE_PRESENT().
