For whomever is curious, I have implemented the new Boost.Contract syntax. Here's large number of examples that now compile with the new syntax: http://svn.boost.org/svn/boost/sandbox/contract/libs/contract/doc/html2/cont...
Wow. This is a powerful new language! How does this relate to the work Matt Calabrese started on implementing concepts in C++11 (see the boostcon video)? It looks like this can't possibly be quite right (can it?) http://svn.boost.org/svn/boost/sandbox/contract/libs/contract/doc/html2/cont... Don't you need a comma after "boost::InputIterator<Iter>"?
Highlights are: * Side-by-side comparison with N1962 (contracts) and N2081 (concepts) syntax: http://svn.boost.org/svn/boost/sandbox/contract/libs/contract/doc/html2/cont... I have also added C++0x-like virtual specifiers (final, override, and new) to Boost.Contract: http://svn.boost.org/svn/boost/sandbox/contract/libs/contract/doc/html2/cont... Side-by-side comparison with Eiffel syntax: http://svn.boost.org/svn/boost/sandbox/contract/libs/contract/doc/html2/cont...
Comments are always welcome :)
* Very impressive! I might even try programming in this language. * How's debuggability (sorry for asking)? * What's a "loop variant?" I've heard of "loop invariants."
(I still have to implement named parameter support (using Boost.Parameter behind the scene) but that shouldn't be too hard. The macros already parse the named parameter syntax using in/out/inout "keywords".)
