Personally I'm advocating for avoiding underscores whenever dashes
can also be used, and whenever they're not needed to distinguish
themselves from dashes (like in target triplets). But this doesn't
make their use "awkward" here of course - it's just my personal
view on it. And maybe, despite the main was sent _to_ just me, it
was really me you meant to ask ...
