— With my configuration, it won't prevent the error

— User invest_with has 1/2 warnings; be careful!
The latest warn was because:
crypto that 1000% works

— Oh sorry

— Generally it' s not a problem since we can move the complete type inclusion in a cpp file. But when I need to use both the templated parameter and the complete A type, I end up with this. It's very limiting

— I hope that c++ modules will improve this situation :)
