Boost :

It turns out that BOOST_TYPEOF_NESTED_TYPEDEF has a problem when used inside
functions on VC8.0 (possibly other compilers as well)
This is because BOOST_TYPEOF_NESTED_TYPEDEF internally defines a member

struct a {
  template<typename T>
  struct b{

VC8.0 doesn't handle this (error C2892: local class shall not have member

It is possible to avoid this problem, but this would cripple
BOOST_TYPEOF_NESTED_TYPEDEF because it would reintroduce the
BOOST_TYPEOF_LIMIT_SIZE limitation on the expression complexity.

The alternative is to disallow NESTED_TYPEDEF inside functions, and write a
note on this in the docs. Is this acceptable?
