BTW, shall I log a writeln() improvement bug ?
It's really confusing, e.g as debug print or logs.
In my opinion this isn't a bug. The nulls are actually printed:

FYI, you don't need the call to `.array` there--`text` accepts
input ranges.

What about `s.until('\0')`?

Another way, if you want to avoid the extra allocation, slice the static
array with .indexOf:

What about `s.until('\0')`?
Example:
auto s = "abc\0\0\0def";
auto t = "blah"

So how can I trim the leading & trailing `\0` from the static
