Peter,

How's the documentation going?  I need it.  I've been trying to
figure out how to call a pointer to member function through a 
pointer, i.e., do what mem_fun does.

I have

 struct Foo { void bar(int*); };
 std::vector<Foo*> foos;
 int *pi;

At the moment I also have 

 for_each(foos.begin(), foos.end(), bind2nd(mem_fun(&Foo::bar), pi));

and thought I'd see if I could do this using your library.  I tried
replacing it with

 for_each(foos.begin(), foos.end(), apply(&Foo::bar,*arg1,lv(pi)));

but no luck.  It would seem you can't dereference arg1 - is that
right?

Mark
