Yes, i could require that, or at the end would do.
However it's trickier to enforce.
Personally I find all kinds of "include" abhorrent.
A "requires" is more sane, and probably the right name
for this feature considering how it works.
In any case I regard "include" as a kind of temporary feature
until a better one can be devised. The relationship between
program structures and the filesystem is always a pain.
A really good design here would be nice. C's method
is the most flexible with the worst modularity properties.
Python import, Ocaml's method, etc, provide much stronger
coupling between "file" and "module" which is also nasty
because it interferes too much with refactoring.
Felix splits "class" and such namespace things off from
the file system. This provides more flexibility, but it
costs as well: a superior pain to do:
include "mystuff";
open mystuff;
although C++ has that too:
#include "mystuff.hpp"
using namespace mystuff;
Another questionable feature can be seen in
src/lib/std/__init__.flx
which just includes everything.
All of this is insignificant if one goes to Literate Programming
but most people hate that because it's hard to configure an
editor to handle it well, let alone an IDE.
I'm not an IDE man although I was an early user of the very first
and easily the best IDE ever producted: Turbo Pascal.
And that revolutionised programming. but it would be foolish
to stand in the way of those who like (or are forced) to use
an IDE. The only way to get LP and an IDE is probably a modified
kind of online WIki thing.
