I know the syntax is confusing, but the + versions can be read as "starts
with?". If you need more powerful stuff, use version ranges.

Adding such a version matcher would be pretty easy. The main problem IMO
would be to distinguish the syntax from others (Ivy deduces the version
matcher from the version only, there is no additional parameter). Maybe we
could use a prefix or suffix to the official syntax. Feel free to open an
issue in JIRA, and even contribute a patch if you like :-)

Any chance of adding a version matcher for the JSR-277 (draft) version
range syntax? I find that one to be pretty intuitive.
