+// Reads the compiled scope back out of the wire format as a mapping from the
+// name the template uses to the JS it resolves to.
+//
+// Older compilers emit the scope as an array (`scope: () => [Setup]`) and newer
+// ones as an object (`scope: () => ({ Foo: Setup })`). Both carry the same
+// information, but the array form leaves the names implicit: they're the
+// `locals` we handed the compiler, in order. Reading those back off the
+// precompile call puts both shapes into the same form, so a test can assert on
+// the scope without caring which ember-source is installed.
