This isn't a formal review, just some initial comments based on a quick test
of the lib.
* I definitely think that the stl.hpp header should be split up to provide
finer granularity (altough possibly retaining a convenience wrapper.)
* Have you read this article by Andrei Alexandrescu?
One advantage of an approach like the above, which I personally value, is
the ability to do const-initialization: vector<foo> const v = make_vec(...);
* Another variant similar to the above is to use a function-template as a
pure "type grabber" and provide a conversion operator for the chaining
proxy. This allows syntax like: container<T> const c = init(c)(..)(..) ;
This technique is used in Leor Z's lib, as I'm sure you're aware. A third
option (also used by Leor) is to have a fully templatized conversion
operator. I'd vote for the "middle road" solution above though.
Would be interesting to hear your opinion and rationale regarding this.
Regardless of implementational technique and syntax finally chosen, I'd
Really like it to support const initialization. (is that the correct term
* What's the reason for removing the enum_* initialization mentioned in your
http://www.codeproject.com/vcpp/stl/PGIL.asp Is something similar planned to
be added later?
boost/call_traits.hpp is included but not used.
* Documentation nitpick:
The "history and rationale" part doesn't have a quick-link from the index.
* I think the documentation for initialization of boost::graph, uBlas etc
should be moved to separate chapters (files). The lib will most surely grow
and a separated structure for adding docs for new components could just as
well be used right away.
* Boost.PP could/should be used to provide configurable upper limits for
number of parameters.
* Perhaps use concept_check to ensure that the default version of
make_insertion only operates on Sequences?
Hope this makes alteast some sense to you, I'll try to tinker with the lib
some more and hopefully return :)
