You can see that if all such functions were listed as programs, it can cause a lot of clutter. Perhaps this may change in the future... I have no idea.

yes,
I understand.
The problem is related to the fact we can't use "EXPORT" with #cas/#end structure, I think, so the function won't listed.
I hope in the future could be a way to get that, as it's very useful!

Thanks again!
