+// Try to instantiate as many implementations as possible.  Finds all
+// implementations reachable via the service manager.  If a given implementation
+// is the only implementor of some service that has a zero-parameter
+// constructor, instantiate the implementation through that service name.  If a
+// given implementation does not offer any such constructors (because it does not
+// support any single-interface--based service, or because for each relevant
+// service there are multiple implementations or it does not have an appropriate
+// constructor) but does support at least one accumulation-based service, then
+// instantiate it through its implementation name (a heuristic to identify
+// instantiatable implementations that appears to work well).
