Well it stands to reason that the Plan 9 code would work that way if Rob Pike made the comment. I'm just wondering if anyone else found this way of coding attractive. Everything I've seen points to "no".
That is not the stated purpose of the tool (to write code in the aforementioned style):
"Include what you use" means this: for every symbol (type,
function variable, or macro) that you use in foo.cc, either
foo.cc or foo.h should #include a .h file that exports the
declaration of that symbol.
I agree 100% with that statement. According to the style, foo.h can never #include anything.
