Well, last version of Loki (0.1.6) includes 'Function' that 'Allows a boost/TR1 like usage of Functor'. It's pretty close to what you may expect from boost.function.

It's already in Loki. You just have to define LOKI_ENABLE_FUNCTION. This adds bool empty() and void clear() to a Functor and bad_function_call exception.

Is there a reason to not use boost types with Loki Functors?
