Well Mathias has already outlined the major reasons. That seems like quite
sufficient documentation. If a developer is performance conscious and notices
one the outlined problems in the codegen he can simply try the force inline
approach and see if it helps. I don't see where a problem could lie there or a
reason for wasting too much time discussing something so simple. Otherwise one
could question any existing part of the language by pointing that it could be
abused (unintentionally or otherwise).
I don't know of a "study" related to forceinline, but in this case it arose as a
(partial) solution to the problems listed by Mathias in the development of the
NT2 (and thuse Boost.SIMD and Boost.Dispatch) libraries. These were discussed on
the NT2 dev mailing list an on #nt2 so maybe someone can present logs of these
discussions if you are interested...
