Unfortunately the argument order is incorrect, so perhaps add `tuple_for_each_` with the correct one and make it variadic.

For old gcc versions BOOST_MP11_HAS_TEMPLATE_AUTO isn't set

3

Old versions of gcc (7.1-8.2) don't define `__cpp_nontype_template_parameter_auto` but only `__cpp_template_auto`. Because of that `BOOST_MP11_HAS_TEMPLATE_AUTO` doesn't get set even though those versions support it. spirit checks both (https://github.com/boostorg/spirit/blob/59515f0e56aebdf958eadab30be99cac8872e723/include/boost/spirit/home/x3.hpp#L19). Would this...

Maybe add mp_set_find

3

In cases a list is a set it is possible to do `mp_find` quicker. Is it worth to add this? ```c++ template using mp_enumerate = mp_transform; template using mp_set_find =...

Single header version of mp11

11

It would be great to have boost.mp11 available as a single header with root namespace that can be defined from outside. This allows to distribute mp11 along with a library...

Improve compilation speed by taking advantage of memoization

2

Mp11 does not take full advantage of memoization, which increases compile time and memory usage. For example for `mp_map_find_impl`: ```cpp template struct mp_map_find_impl { using U = mp_inherit; template static...

mp_map_find seems not working properly using g++

4

The code is at https://godbolt.org/z/KvjecnTe3. The code can be compiled if switching to clang 13.0.1, but gcc 11.2 or the trunk version fails. Interestingly, if I comment out line 22...

boost::mp11::mp_list can't be used as base class for transition table within msm::front::state_machine_def

I just wanted to modernize my code - and try to use `boost::mp11::mp_list` instead of `boost::mpl::vector` in my FSM definitions. Simplified code is as follows: ``` #include #include #include #include...

Assume we want to invoke tuple_for_each or tuple_apply on the keys or values of a map. We can encode our projection inside the function object passed as argument, but it...
