design of large modular projects in nim?

Apparently, [Araq has pointed out](https://forum.nim-lang.org/t/2829#17969) 
that `nimsuggest` actually does track `includes` properly, but editors do not 
often make use of this feature. Bummer. But this would enable the 3.B solution, 
reducing the hoop-jumping by one layer :)
