A few minutes ago, I have a same issue. I need add some enum values as a compile option.

Now I have something like this:
version (Parser) {
        enum Application = "parser";
}
version (Report) {
        enum Application = "report";
}

But would be nice to have posibility to add same value as a compile parametr, so I could have code like this:

enum Application = __traits(getParametrValue, "MY_APPLICATION_NAME");

and compile code with some args for eg.: -VMY_APPLICATION_NAME=parser

You can solve this using import expressions.

---parser/config.include---
enum Application = "parser";

---report/config.include---
enum Application = "report";

---main.d---
mixin(import("config.include"));

---Makefile---
parser:
    dmd main.d -Jparser

report:
    dmd main.d -Jreport

Thanks, this is usefull :)
