[basic.pre][basic.link] Names have linkage

AlisdairM · AlisdairM · commit 71b8b7eab228 · 2025-07-27T10:57:23.000-04:00
An essential property of names is that they have linkage.
Move the statement that names have linkage up from [basic.link]
to [basic.pre] where the term `name` is defined, and before
the references to linkage of names in the clauses between
[basic.pre] and [basic.link].
