Imports

There are also two ways to get values out of a namespace, such as example defined above. First, it might be used in a destructuring assignment like the one below. This assignment's target looks like a list, where each entry specifies one of the names exported by the block and what it should be assigned to. The element can be either a single name, like b, which gives both, or an aliasing expression like b2⇐b. In this case, the value b from the namespace is used, but it's given the name b2 instead of b. Imported names can be repeated—but the variables defined can't—and all the names can be spelled with any role (the role is ignored).

If aliasing with ⇐ is never used, the names can be given as a strand with ‿.

If aliasing with ⇐ is never used (or each use is parenthesized), the names can be given as a strand with ‿.

c‿a ← example

The arrows ⇐ used for importing don't indicate that the surrounding block is a namespace or export variables. However, a single statement can both import and export, if it's a destructuring assignment and the main assignment arrow is ⇐.
