Calls to swap in the library don't properly describe context

In the following sections:

• iter_swap: [alg.swap]/7
• pair::swap: [pairs.pair]/30
• optional::swap: [optional.swap]/2
• tuple::swap: [tuple.swap]/2
• variant::swap: [variant.swap]/2
• possibly others

We describe swapping as either doing swap(a, b) or otherwise calling swap - which in the library wording always means ::std::swap, since we don't otherwise describe what happens here. But in these contexts, what we mean is that we're calling swap in the context described in [swappable.requirements]/3 (i.e. using ::std::swap; swap(a, b)). This is done correctly in the description for is_­swappable_­with in [meta.unary.prop].

Is updating all these sections an editorial fix (this is the behavior we actually mean, just poorly specified) or does this require a library issue?

Start by reading the cited sections—iter_swap, pair::swap, optional::swap, tuple::swap, and variant::swap—alongside [swappable.requirements]/3 and the is_swappable_with wording in [meta.unary.prop]. Check whether other library clauses use the same description; done means the applicable wording consistently specifies the intended swap context and the editorial-versus-library classification is resolved.
