A scope table says why

Claim: a member's scope is a table of in, later and out rows, and every row says why.

• Grade: convention, untested.
• Evidence: the table on the front page and in each member; signal the structure in the standard for a table over prose.
• Check: scope-table (exact: the header, the kinds and their order, a reason in every row).
• Reader styles: none.

What it asks

• Under a heading Scope, a table with the header | | What | Why |, so the overlap check can read it.
• The first cell is in, later or out, and the rows come in that order.
• An out row names the member that holds the thing, or says that nobody does.
• The Why of a row is its reason, not a restatement of the What.

Why

• A reader sees the boundary at a glance: what is held, what waits, what is elsewhere.
• A program can read the form, which is what makes the previous principle checkable.
• A row with a reason can be disputed; a row without one can only be accepted.

Limits

• No experiment compares this form with prose for stating a scope.
• The check decides the form and not the truth: it cannot tell whether a row is accurate or its reason good.
• The shape is scope table; it has one filled example.
