[Boost-announce] Formal Review: Typeof

The formal review of  Arkadiy Vertleyb and Peder Holt's Typeof library
began on May 20th 2005.(Apologies for not posting this on
boost-announce sooner).The review period will continue until
the 30th of May.

The proposed Typeof library emulates the functionality of the non-standard
'typeof' operator,  and incomplete implementations of decltype and the
proposed 'auto' declarator , described in
http://www.osl.iu.edu/~jajarvi/publications/papers/decltype_n1478.pdf.
It is commonly acknowledged that this type of functionality is sorely
needed and should be standardardised in the language.

For compliant compilers the library requires some help in the form of
registration macros but, because use of typeof is by its nature most
likely in generic libraries, it is expected that this can often be done
by the library author rather than the user. In some cases the compilers
capabilities (by means of extensions and even compiler bugs)have been
used to remove the need for registration. However, for portability and
in order to test emulation mode on the compilers where it is available
but not used by default (VC7.1, GCC etc), #define BOOST_TYPEOF_COMPLIANT
[see note  *1*]. Testing the emulation is useful, even on compilers that
provide a better option, to get a rounded view of the library and its
capabilities.

I hope you will find time to write a review of the library, which is
available at:
http://boost-sandbox.sourceforge.net/vault/ , typeof.zip

The system has been tested with the following compilers:
MSVC 6.5/7.0/7.1/8.0;     [see note *1* regarding VC7.0 and VC6.5]
GCC 3.4.2

(The following is a quote from :

Here are some questions you might want to answer in your review:

What is your evaluation of the design?
What is your evaluation of the implementation?
What is your evaluation of the documentation?
What is your evaluation of the potential usefulness of the library?
Did you try to use the library?  With what compiler?  Did you have any
problems?
How much effort did you put into your evaluation? A glance? A quick reading?
In-depth study?
Are you knowledgeable about the problem domain?

And finally, every review should answer this question:

Do you think the library should be accepted as a Boost library?  Be sure to
say
this explicitly so that your other comments don't obscure your overall
opinion.

*1*
MSVC6.5 and VC7.0 are not supported by the BOOST_TYPEOF_COMPLIANT macro
