I would have expected the following to work:

int[] d = [1,2,3,4,5,6,7];
d[] = d.filter!(x => x > 3)[];

Where the rhs could have been assigned to the lhs.
Unfortunately this gives the following:

Error: cannot implicitly convert expression (f.opSlice()) of type
FilterResult!(__lambda2, int[]) to int[]



For now, the only idiomatic solution I could find is this roundabout way:

auto t = d.filter!(x => x > 3).copy(d);
d = d[0 .. $ - t.length];
