Let's say you have a range with struct, but some of the struct

Is there a standard function in Phobos to remove duplicates?
My first thought was "uniq", but it can't really do it like
that, but it doesn't work.
See: https://run.dlang.io/is/IcFEtw
Is there another function in Phobos that perhaps would work?
I can of course write my own function, but if there is a
standard function that can do it, then I'd rather use that.
range
.array.sort // make equal elements be adjacent
.chunks!"a==b" // get a range over those equal elements
.map(e => e.front); // get the first one
should work, possibly not the most efficient way to do it though.
I don't know off the top of mu head if there are any to preserve
the order or the original range.
