I finally managed to find how to tackle the todo on assertion:
- preserve the current scheme to implement an assertion: delegating to a function to allow overloading and optional parameters
- but make it so that the user condition is evaluated first (and not SourceLocation check point object...) to make debugging easier.
 
There is no change on existing assertion macros. But if you have written some custom assertions, you will need to update the code. See CPPUT_BEGIN_ASSERTION_MACRO() documentation in testinfo.h for an example on how to update your existing assertion code.
 
Let's me know if you run into any issues as I was not able to compile this on all the usual compilers (only tested msvc71 & msvc80).
