Hello,

I'd like to ask for formal review of (candidate) Boost.PolyCollection, a 
library providing
fast containers of polymorphic objects:

https://github.com/joaquintides/poly_collection
http://blincubator.com/bi_library/polycollection/?gform_post_id=1643
http://rawgit.com/joaquintides/poly_collection/website/doc/html/index.html

Typically, polymorphic objects cannot be stored directly in regular 
containers and need
be accessed through an indirection pointer, which introduces performance 
problems
related to CPU caching and branch prediction. Boost.PolyCollection 
implements a novel
data structure that is able to contiguously store polymorphic objects 
without such
indirection, thus providing a value-semantics user interface and better 
performance.
Three polymorphic collections are provided:

* boost::base_collection
* boost::function_collection
* boost::any_collection

dealing respectively with classic base/derived or OOP polymorphism, function
wrapping in the spirit of std::function and so-called duck typing as 
implemented by
Boost.TypeErasure.

The library compiles and runs succesfully in Visual Studio 2015, GCC 
5.2.1 and
Clang 3.7. Ion Gaztañaga has kindly volunteered to act as the review 
manager for
(candidate) Boost.PolyCollection.

Best regards,

Joaquín M López Muñoz
