tl: dr: please, no
We have put quite some effort into fighting default DMD behaviour
of -unittest simply adding to main function and not replacing it.
Initially many applications did run tests on startup because DMD
suggested it is a good idea - some rather bad practical
experience has shown this was a rather bad suggestion. Accidental
tests that start doing I/O on productions servers, considerably
increased restart times for services - that kind of issues.
And if you suggest to build both test and normal build as part of
single compiler call (building test version silently in the
background) this is also very confusing addition hardly worth its
gain.
Just tweak your editors if that is truly important. It is not
like being able to click some fancy lines in GUI makes critical
usability addition to testing.
