Is there a way to filter the collection at the foreach-level to avoid

Here's how I would do it:
foreach (k, v; coll) {
if (k == unwanted) continue;
...
}
You still have an if, but the actual loop body doesn't have to be
nested, so it's easy to follow the control flow.
Alternatively (if you're ok with this sort of thing):
foreach (k, v; coll) if (k != unwanted) {
}
It's actually visually shorter than doing the filter.
And the benefit to using the if statement over the filter wrapper is
that the compiler has to do a lot less work.
