+While it is not recommended practice, sometimes you might need to bind a
concrete class without having an interface to which to bind it. For
instance, you may have a class you need from a library whose source you do
not control, and therefore cannot abstract an interface from the class. In
this case, you need only bind the class without binding it _to_ anything,
like so:
+{{{
+ @Override
+ protected void configure() {
+ bind(MyConcreteClass.class);
+ }
+}}}
+Guice infers that the class is both the key type AND the implementation.
