I apologize in advance if something along these lines is already available; however current public documentation doesn't mention such a facility and a brief glance into SVN did not reveal one either... product_view Description: provides a view of a Cartesian product of multiple sequences. Modeled after zip_view in that it expects a sequence [of length n] of sequences S1...Sn as its argument and lazily generates a sequence [of length Prod{1...n}( size< Si > )] of sequences S1[1]...Sn[1] through S1[n]...Sn[n]. Whew... I know I can write better documentation than that if I put my mind to it :( I have attached a proof of concept implementation and a short test program. The code appears to compile and work with MSVC 2003 & 2008 and with GCC 4.2. It is not [yet] Boostified. My use case: I needed this adapter to write a dynamic dispatcher for a known set of template instances (poor man's dynamic template instantiation). Regards, ...Max...
