A.6.3.RT.OE:4.6 - Return the expression for its next use
Keep the expression, the conventions that another user needs and the relation to the content from which it was prepared. Include a changed assumption, omission or unresolved interpretation where it can alter the next operation.
The next use can continue the construction, communicate the result or apply it in another situation. Reopen the expression when that use requires a relation it no longer makes available. Stop preparing it when it supports the present operation adequately.
