Can someone explain this syntax? Looking at the Axiom .spad files,

`I see that it has general usage +/[...some list construction...].

`It is old syntax for reduce and should go away.

`

Rather, I think it is the equivalent BOOT syntax for reduce (right,
Gaby?) and I think it should stay in BOOT where there is no static
type checking. But I agree that it should not appear directly in SPAD

`files. This expression returns a syntax error in the Axiom interpreter.
``
`If I recall correctly, there a few other places in the Axiom library code
where old BOOT syntax appears (perhaps for efficiency or to avoid
awkard type manipulations) but should be really be replaced by a

`more appropriate Spad idiom.
