What?
Well I guess that strictly speaking a #include statement is just an
instruction to a compiler to include some content whose location is defined by
a string. Now I don't know if the language standards mandate that those string
represent file name paths, but it's not inconceivable that they are just
lookup keys to some content somewhere. And that content is inserted to the
source (which doesn't necessarily have to be in a file system file either in
our imaginary implementation; it could all be memory buffers) and then fed
(somehow) to the compiler.
