[Boost-users] [mpl] nested lambdas?

Suppose I'm tying to build a nested lambda expression, like so
(typename...::type omitted for simplicity):

lambda<higher_order_func<lambda<foo<_1> >, _2> >

- Is this legal?
- Does the _1 refer to the first argument of the inner lambda, or of
the outer lambda?
- Can the above be overridden? I.e. what if I want to refer to the
arguments of both lambdas within the inner lambda?
