The boost::variant library, currently available at
Sourceforge/boost-sandbox, is ready for a formal review. We expect the
final version to be ready within a day or two, at which point we will place
a zipped package at the Boost's File section.
The formal review (scheduled by Thomas Witt) will tak

I agree. The traffic-light metaphor falls apart when you add black.

Hi all,
Anyone who was working on it - what's the current state of play? The flurry
of mail on here a while back seemed to fizzle out. Is that because
development has stalled?

Hi!
I just updated the regression tests for AIX for both Visual Age 5 and
Visual Age 6 and I will try to update at least once a week until Toon
gets access to another maching.
On a side note, how do the compiler version numbers get into the
status tables? They don't show up for AIX and the com

Hello boosters,
I've justed stumbled across a problem when using the BOOST_CLASS_TEST_CASE
macro in a special way.
I am using class based test cases and want to run every testcase from a
clean environment, i.e. I need to create a new instance of my test class
for every test case.

Hello all,
We've noticed that normal_distribution using polar
method, rather then Box-Muller.
Is there a particular reason for not using Box-Muller?
Looks to me like a quite an easy way to improve performance.
The method with source code is described in Numerical Recipes.

It will prevent you to encounter this situation (if peak_of() is used only
with smart_ptr<>s). peak_of() won't have to deal with it.
It would also be possible to assert the parameter of peak_of() is valid, bu

We've discussed making boost::ref/boost::cref work for arbitrary functions
objects before. I just committed a version of ref.hpp that supports this
ability to the sandbox. With this code, you can write:

Hm...
- Function if the compiler supports PTS;
- If not, then the user would have to type in something like:
Function0.
Looks good. Another (slightly offtopic) thing. I attempted to use
function_traits with a member function type. GCC spat out errors, and
looking at the source code I don't think

Can you elaborate as to what the difference between Box-Muller and the implemented method is? As far as I understand Box-Muller it is just the implemented algorithm.
