You're welcome. Nim core devs are **_very_** willing to work with any and all comers on pull requests to improve documentation. Ignorance by otherwise reasonably patient and resourceful newcomers is **_not_** easy to simulate (in any project, really). In some ways it's a resource that decays with value as people learn their way around.
I agree that foreign function interface helper procs like those mentioned probably deserve a section somewhere, probably linked to from the area you mention. I mean, there is the `system.nim` module documentation, but it's kind of its own problem area.
