While using zip_iterator I encountered some minor bugs. Bugs: The include guard is broken (the #define has been omitted). The function "tuple_equal" causes multiple-definition linker errors. Patch: Added missing #define to header guard. Added missing "inline" keyword to "tuple_equal" definition. Please find attached the patch file.
