[Boost-users] typesafe typedef that is not implicitly convertible

I am unable to find it now, but I thought I saw that there is a boost 
way to define a typedef using a unique class that cannot be implicitly 
converted to another type.  Thus,

typedef int Foo;
void bar( Foo a );

would compile only with bar( Foo(3) ) not bar(3)

Is this capability in Boost 1.33 or am I hallucinating?

Thanks,
Phil
