I need to ensure that range passed to function is SortedRange to use
binary search. I did something like:
static if(!__traits(compiles,
{
ElementType!(typeof(data)) element;
auto d = data.trisect(element);
}
)) assert(0, "DataRange shall be SortedRange");
It works for me, but in fact it checks if the type of 'data' have
'trisect' method and conception of SortedRange is something more than
having 'trisect' method.
I remember there is(?) some way to get general type of template (i.e.
SortedRange instead of SortedRange!int), but can not find it.
