It depends on whether --eval is going to be used to any reasonable 
degree. I don't think it is, so config files are overkill.

But tango doesn't deal with string.

You could add at the top:
static if (!is (string)) alias char[] string;

The only difference due to different phoboses is using FILE* rather than 
struct File.
