Well, I saw it used quite a lot one program, and it brought to light
that there was an error in the compiler vendor's implementation of
Text_IO;
We made a fix to the implementation, and submitted it to the vendor,
who rejected our solution because of some AI (I don't remember the number).
After four years of waiting, I gave up on the vendor ever fixing it.
I'm no longer on that program, but I think they're still using my
"workaround."
