Is there a general function for transforming a range back to the
original type? If not, would it be possible to create one?
You mean that if you have something like
auto range = getRangeFromSomewhere();
auto newRange = find(filter!func(range), value);
you want to transform newRange back to the same type as range?
No, I want to transform newRange back to a collection, the same type as
the original collection. I was thinking something like this:
Collection c = new Collection();
c = c.filter!(x => x < 3).toCollection();
Why can't the last line be:
c = new Collection(c.filter!(x => x < 3));
or more generically:
c = new typeof(c)(c.filter!(x => x < 3));
?
