rdmd and shebang limits

[Andrea Fontana]

Yes I read rdmd but I didn't notice @cmd that was on dmd help, my
fault!

However as I said in my second post, probably it won't solve the
problem: shebang is useful if  you can write a "self-contained"
script, something that fits inside a single file.

I agree with Andrei. It would be a good solution for my case and
it shouldn't break anything.
