Hi All
Is it dangerous to write static Boost.Functions or Boost.Lamda placeholders
in a multi-theaded
context? I think that might be a really stoopid quesion - I'm just checking!
In C++03, local static anything is dangerous,
because the initialization is not guaranteed
to be thread safe.  It's safe in C++0x and
both Boost.Function and Boost.Lambda are
safe with parallel reads.

eg,
#include 
#include 
void f( )
{
    namespace ll = boost::lambda;
    using boost::function;
typedef std::pair int_pair;
static ll::placeholder1_type x;
    static function second = ll::bind( &
int_pair::second, x );
}
