digitalmars.D.bugs - Cannot default template parameters with member types of other parameters

The compiler complains "no property 'value_type' for type 'R'no property

    template FilteredNotionalRange(R, V : R.value_type) { class
FilteredNotionalRange
    {
      . . .
    }}

Is this a bug, or a missing language feature?

That would be specialisation then. Not default? 
Bit confusing, but the templates apparently don't follow the rest of D when
specifying defaults. 

: == specialisation
= == default

Unless the spec is way out of date with reality and I've been doing this all
wrong - no wonder my tests don't work :)
