+/**
+    Inserts the examples defined using a `Behavior` into the current example group.
+    The shared examples are executed at this location, as if they were written out manually.
+    This function also passes a strongly-typed context that can be evaluated to give the shared examples extra information on the subject of the example.
+
+    - parameter behavior: The type of `Behavior` class defining the example group to be executed.
+    - parameter context: A closure that, when evaluated, returns an instance of `Behavior`'s context type to provide its example group with extra information on the subject of the example.
+    - parameter flags: A mapping of string keys to booleans that can be used to filter examples or example groups.
+                  Empty by default.
+    - parameter file: The absolute path to the file containing the current example group. A sensible default is provided.
+    - parameter line: The line containing the current example group. A sensible default is provided.
