Concerns about use of word "check" is pure pedantry, but I'm not convinced about including this as a MaskCheck

[acl-cqc]

do an is-borrowed before too, and return two booleans

[ss2165]

don't see the reason, this is not an execution test, just of building the op

[acl-cqc]

Well I was thinking you could use this in the execution test...

[ss2165]

the general pattern is to keep the tests very independent and I would like to maintain that

[aborgna-q]

The type order is a bit weird, with the array in first place for the input but 2nd in the output.
But I see that we're doing the same with borrow so 🤷
