[Boost-users] Lambda expressions

I posted this question a few months ago, but I got pulled away to deal with
more pressing work issues. So here it goes again:

I'm trying to use lambda expressions to implement 'twice'. So I came up with

typedef mpl::apply<_1, mpl::apply<_1, _2> > lambda_type;

typedef lambda_type<boost::add_pointer<_1>, int> result_type;

When I look at result_type, I get is_same<result_type, int*>::type::value
evaluates to true. I expected that is_same<result_type, int**>::type::value
would evaluate to true. Why is my lambda expression 'lambda_type' only
returning it's second argument??

Manson: My philosophy is:  Don't think.  I don't believe in the mind that you think with and scheme with.  I don't believe in words.

Reporter: If you don't believe in words, why do you use so many of them?

Manson: Words are symbols.  All I'm doing is jumbling the symbols in your brain.  Everything is symbolic.  Symbols are just connections in your brain.  Even your body is a symbol.
