I'm finishing a fast (I just don't see a faster way) and garbage-free 
CTFE-capable wrapper. But it requires IDL to be written for every C 
function.

It already performs C-arrays (with length or end element) to D arrays 
conversion and UTF-8/16/32 conversion (usable for WinAPI *W functions). 
It will soon wrap functions like `GetCurrentDirectoryW` where it will 
call C function twice (if it will not guess with buffer size at first time).

For easy understanding of how does it work look at `examples/c.d` - this 
is a bunch of test C sources. D sources obtained from it are in `out` 
directory.
