You can use std.algorithm.filter on its result. Then when it
would iterate to
something which doesn't match filter's predicate, it skips it.

That will do the filtering correctly - but what I was hoping was
to actually prune at the directory level and not drill down to
the files in of an unwanted directory (e.g. .git). The problem
with this and what I'm trying to overcome is accessing lots of
files and directories recursively all of which I want to skip.
Much like there is a *followSymlink* it would be nice if a
predicate were accepted to *followDirectory* in general or some
way to cause that.

static bool desired(string m) {
bool unwanted = match(m, _uninterestRe)? true : false;
writeln("Is unwanted ", m, " ", unwanted);
return !unwanted;
}
static Regex!(char) _uninterestRe = regex(`\.git\b`);
filter!(desired)(dirEntries(root, SpanMode.depth))) {
...
}
