It's conceptually equivalent to C++ being able to #include C files. I was in the 
business when C++ came out, and am pretty certain this was crucial to C++'s 
early adoption success. ImportC cannot be as as good as that (preprocessor 
issues), but it's closer than any of the other solutions I've seen.

For another language doing the same thing, see Kotlin, which can seamlessly 
interact with Java, and this has been crucial to Kotlin's adoption.

How is ImportC unique? No other solution I've seen is as simple as:

     import mycfile;

These things matter.


Feel free to compare ImportC with other existing solutions, and post your results!

Note that ImportC can inline C functions, and ImportC code can import D code and 
access D constructs. Who else does that? (Not even C++! Maybe Kotlin can.)
