Does boost have something like small_function (with customizable buffer size)?

 I tried googling, but I found nothing.
I presume that that means it does not exist, but it is possible it is maybe
hidden under some name I could not think of.
I am ok with using internal header of some library in case it is code that
is covered by tests.

Ivan
