I have a question on usage of BitFlags, described here:
https://dlang.org/library/std/typecons/bit_flags.html
and/or on bitop
https://dlang.org/phobos/core_bitop.html#.bsf
A similar example to the bit flags example is given here:
[code]
import std.typecons;
enum Rs : ubyte

I don't know what's going on there. Such an assertion does not seem in line
with what Walter has typically said on the subject.
Thinking about it, I do vaguely recall a discussion someti

and works now
