`dmd -i -run` will run the majority of files and d allows for the 
first line of code to be `#!` which on linux makes it a "script"

Add -unittest and -l and its probaly most of what you want, its 
not perfect but d has a fantastic compiler api by comparision.

id suggest having whatever makes your executable runs should be a 
`#!dmd ...` if you need linker flags or whatever just look them 
up and put them there; from a clean slate thats what I suggest

if you have something complex `std.process` is a bit verbose but 
its how you call executables(like the compiler), append some 
strings together and throw it at it. I use a wrapper I copy and 
paste around.

If youve only used dub, your probably used to an src folder, you 
mostly just flatten your folders by 1 and it makes `-i` 
automagically work, if you then want folder of executables try to 
get by with `./foo/bar.d`.

it can be a bit tricky to be that simple so you may need to do a 
build script; Im not following my own advice here but this is 
what I was doing a year ago see biuld.d and exmaples/ :

resent and better example with his parin lib.(maybe)
