What's the ultimate setup for vim?

[Jay via Digitalmars-d-ide]

i've installed dutyl and d.vim (not dsnips though, not 
interested). i guess now i need to set 'makeprg' (to 'dub build' 
or 'rdmd --build-only' if dub.json isn't present) and 
'errorformat'. this is somewhat uncharted territory for me so i 
decided to look for existing solutions. didn't get much out of 
google so here i am. please post your whatever you feel might be 
useful and i'll try to sum it up and add to the wiki page.
