Did the implicit conversion from special slice expression to static array ever work?

It looks like the docs were merged but the compiler pull was not 
merged:

Before I found that I implemented `arr[e .. e+b]` for a simple 
variable `e`:
https://github.com/ntrel/dmd/commits/slice-size

I think at least that should be supported, probably the most 
common of all the non-constant index forms. But the original pull 
works for lots of other side-effect free expressions, besides the 
other forms.
