I'd think so too. Perhaps a reason for this confusion is the choice of
syntax for version constraints? I don't know how much work and hassle it
would be to change/expand it, but it might be worth at least considering
adopting a less ambiguous syntax. One source of inspiration could be Apache
Ivy, where ranges are specified much like in math: `[3.14,)` for any
version >=3.14, `(3.14,4)` for >3.14 and <=4.
I'm not a Pacman developer and I only manage a small handful of packages,
which don't currently use version constraints, so please disregard me if
I'm completely clueless. :)
