IIUC Aldor does not suport "failed" (with Spad notation) as a type,
which leads to massive source changes (this is in the language
differences page).

Aldor does allow 'Union(a: T, failed?: 'failed'), which might be similar enough. Tangentially, what would be the issues with switching the algebra code to use
Partial instead of the Union?

I would love to see such a change and I would happily help in this
endeavour.

I would like FriCAS to move away from "failed" and choose Haskell style
"Maybe" instead.  This topic has been discussed before, I wonder if
Waldek's opinion has changed.
