Yes, it works. Thanks a lot.
However I still dont get it, why dmd generates all sources
instead of just public symbols and functions declarations
A number of features do not work if not all of the source is
available. In
particular, functions can't be inlined if the compiler doesn't
have their
source, and any function which is used at compile time (using
CTFE - compile
time function evaluation) needs its full source and the source
of every
function that it calls. So, in general, it's pretty crippling
to not have the
full source available. Also, templates tend to be used quite
heavily in D, and
because templates aren't actually instantiated until they're
used, their
entire source must be in the .di file regardless, making it so
that you _can't_
hide their code (C++ has exactly the same issue). So, in
general, .di files
don't make a lot of sense.
But if all that anyone is doing is calling the functions at
runtime, and it
doesn't matter that they're not inlinable, and you don't need
any of them to
be templated (or it's okay for the few that are templated to
have their full
source in the .di file), then you can strip out the function
bodies in .di
files, and that _can_ be useful if you really need that, but
pretty much no
one's going to do that unless they have to (or just don't
understand what they
lose by doing so).

Thanks for explanation.
