With the caveat, of course, that the recommendation to "leave a

a better way to do that (similar to C# KeepAlive). I made an
[attempt](https://code.dlang.org/packages/keepalive), but I
think it's not guaranteed to work, I've already found ways to
prove it fails.
For the moment I am personally quite happy
with any reasonable workaround
(use an object in the end of the main function,
put the reference to an object into some AA, whatever),
because now I firmly understand,
that the source of strange GC behavior
is DSE optimization (in this case).
