ImportC is deprecated as everything in D is deprecated and 
abandoned. No link works, every download link is broken as no one 
cares. All D code is always full of bugs and needs to be 
corrected by the user before trying to run it, in order to 
realize that it wasted time.

ImportC is highly experimental and was announced far too soon.

If you look at the last release a very large number of the bug fixes 
were for ImportC specifically.

ImportC is an interesting, and possibly useful feature..to a 
select few, but ALL will have to carry it.

IMO...ImportC will be D's biggest mistake.

Guys I think Ali is right... The post was meant as an April 
fool's joke... It was pretty badly mistimed though, at the time 
of his posting, it was 3rd April in my place, and undoubtedly 2nd 
everywhere else

Found this thread by googling `dlang sppn.exe`. For the record, 
it can be obtained from sppn.zip here:
http://ftp.digitalmars.com/

I didn't have it for some reason even though latest dmc is 
installed.

 I didn't have it for some reason even though latest dmc is 
 installed.

I then got some weird errors building druntime:

std::array not supported by DMC
std::basic_string_view not supported by DMC

I figured that dmc was not correctly installed (not sure why). So 
I downloaded dmc.zip which fixed it.

Better write something in D.
And write something in C/C++/Python.
And have some form of communication between both.

I don't know about Python, but I regularly write D code that interacts
with external C libraries and have not encountered any major problems.
You just have to put `extern(C)` in the right places and make sure you
link the right objects / libraries, and you're good to go.

So far I haven't actually tried integrating non-trivial C++ libraries
with D yet, but I expect it will be similar unless you're dealing with
C++ templates (which are not compatible with D templates) or multiple
inheritance, which D doesn't support.
