It's missing a few advantages of Boost.Phoenix-like approaches:
  - can happen at the expression level and not just statement level. 
This also means the function does not necessarily need to be named.
  - does not require listing all variables to bind from the scope
  - can be quite more concise for simple tasks.

There is also the polymorphism thing: functions generated by Boost.Local 
are necessarily monomorphic, unlike Boost.Phoenix and global functors.
