I dont think Walter has managed to include that into dmd yet so would probably be easier to have a live stream (video stream not water stream)

That is a bug. No, it does not. The compiler doesn't know about private imports of separately compiled modules. Okay, the compiler could gain that information, but it does not, since it is not required. In many cases, the compiler could detect these issues. Detecting these would be a reasonable, if low priority, enhancement. The problem if it detects it in an implementation-defined manner is the source code is no longer portable. ... If the result of compilation provably won't *run* anyway, what's the problem with a compile-time error? Right. It's like the compiler warning you if your program starts with assert (false).

C#'s model of assemblies and metadata seems more capable. for instance there's no need for header files, that info is stored in the metadata of the assembly. D can do the same thing - it can use the source of the module directly, or it can use a hand-generated 'header' file, or an automatically generated 'header' file. The latter is semantically indistinguishable from compiling the source module to a metadata file. I originally considered having D write such a metadata file, until I realized I didn't have to invent a format and a writer and reader for that format. I could just use the D source code notation as a metadata file and reuse the existing code. The D system has a major limitation, though -- you can't split the source for a module across multiple files. Which pushes you towards enormous source files. It's more restricted than both C# and C++ in this respect.

The current organization of DMDFE is totally inconducive to D's module system, which I find ironic.

Doing so would require full blown data flow analysis, which the front end is not equipped to do.

One somewhat weird issue that we may have to face at some point is that
Posix functions whose behavior was changed have had the symbol for the
new function changed to _blah$UNIX2003, with the old function left in
place. Since D can't declare symbols like this, we may end up having to
add shims in C or post-process object files if it turns out that the old
implementation of a function isn't sufficient. I'd love to hear of a
better solution here.
extern(C) void __identifier(blah$UNIX2003)(int);
That would be awesome.
A beneficial side-effect is that I can finally get rid of all those
mixins that are just doing this:
mixin(`void `~name_of_fn~`(int a)
{
// ... rest of function ...
}`);
I had absolutely no idea that this could be used to generate symbol
names that are illegal in D.

I don't think he's generating illegal symbol names. He's just sick of
having to specify the whole function in a string when all he wants to
change from instantiation to instantiation is the name...
