Re: [Boost-users] [bind] Possible to use variadic templates with bind?

An interesting puzzle. I tried to apply the 'Indexes' technique shown in the bind implementation section of

http://osl.iu.edu/~dgregor/cpp/variadic-templates.pdf

and ended up with the following:

#include #include

template struct int_tuple {};

// make indexes impl is a helper for make indexes template struct make_indexes_impl;

template struct make_indexes_impl, T, Types...> { typedef typename make_indexes_impl, Types...>::type type; };

template struct make_indexes_impl > { typedef int_tuple type; };

template struct make_indexes: make_indexes_impl<0, int_tuple<>, Types...> { }; [snip] That make_indexes was the inspiration for:

http://svn.boost.org/svn/boost/sandbox/variadic_templates/boost/mpl/package_... One additional feature of package_range_c is the the order of the indexes can be reversed. Useful if you want to reverse the order of a mpl sequence. -regards, Larry
