          Issue ID: 24376
           Summary: ImportC: .di generator outputs D keywords for members
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: ImportC
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: dave287091 at gmail.com

This is already noted as a limitation of ImportC (the mismatch in keywords) and
in D code you can work around it using __traits. However, in the .di generator
you instead get a parse error:

C code:

struct foo {
    int version;
    const char* function;
    int uint;
};

.di file:

// ...
        struct foo
        {
                int version = void;
                const(char)* function = void;
                int uint = void;
        }
// ...

Trying to import the .di file will then fail.

I think ideally you solve this with adding a mechanism for D identifiers to
have the same name as keywords. A new kind of string?

Another way to go is to have the compiler rename identifiers that are D
keywords when importing C code (say by appending an underscore). Could also
only do that in the .di generation, but then importing the C code and importing
the .di file are different.
