I want the compiler to generate both documentation (-D) as well as the AST Json file (-X) without having to worry about being able to actually compile the provided D files.

e.g.

ldc2 -o- -c -X -D --oq file.d

However the above command can produce errors such as:

Error: cannot find input file `yadayada.d`

Is there a way to do such a thing currently, since I'd rather not have to deal with having compilation errors when I just want the ast + comments?
