I assume you compiled with LDC and used pragma(inline, true). 
Have you had a chance to look at what 
`-fsave-optimization-record` gives you? (This was adde to LDC 
master 3 days ago.) That may give some insight as to why it was 
not vectorised, e.g. bounds checks not removed.

I dont think we need a new language feature for this.
