The way I would have written it is:
auto result = foobars.filter!(fb => nums.all!(n => (fb.x *
fb.y) > n))
.filter!(fb => nums.all!(n => fb.x < n &&
fb.y < n));
For the lame example I gave, something similar occurred to me
at first; but then I thought 4 `filter`s (assuming `all` is
simply a `filter`) might be non-idiomatic as it might incur
some performance penalty.
Note that this can easily be rewritten with only one `filter` and
one `all`:
auto result = foobars.filter!(
fb => nums.all!(
n => fb.x * fb.y > n
&& fb.x < n
&& fb.y < n));
