To reproduce:
(1) -> (x~=y)$Expression INT
The function not is not implemented in Expression(Integer) .
Since the definition of ~= is apparently (at least according to
hyperdoc) provided by BasicType there is a good change that this
problem occurs in many other domains. The problem seemed

Interesting. It definitely does work in .spad files (search for ^+\[).
In any case, as written it's left to right. There's an argument that it
should be undefined - ie require an associative argument (for parallel
accumulation) but that is likely to be more work than I have time for at
the
Can it be that this /-fold-notation is interpreter-only in FriCAS?
